Synopsis

# Documentation

class Semigroup a where #

The class of semigroups (types with an associative binary operation).

Instances should satisfy the following:

Associativity
x <> (y <> z) = (x <> y) <> z

Since: base-4.9.0.0

Minimal complete definition

(<>)

Methods

(<>) :: a -> a -> a infixr 6 #

An associative operation.

>>> [1,2,3] <> [4,5,6]
[1,2,3,4,5,6]


sconcat :: NonEmpty a -> a #

Reduce a non-empty list with <>

The default definition should be sufficient, but this can be overridden for efficiency.

>>> import Data.List.NonEmpty (NonEmpty (..))
>>> sconcat $"Hello" :| [" ", "Haskell", "!"] "Hello Haskell!"  stimes :: Integral b => b -> a -> a # Repeat a value n times. Given that this works on a Semigroup it is allowed to fail if you request 0 or fewer repetitions, and the default definition will do so. By making this a member of the class, idempotent semigroups and monoids can upgrade this to execute in $$\mathcal{O}(1)$$ by picking stimes = stimesIdempotent or stimes = stimesIdempotentMonoid respectively. >>> stimes 4 [1] [1,1,1,1]  #### Instances Instances details  Since: base-4.9.0.0 Instance detailsDefined in Data.Semigroup.Internal Methods(<>) :: All -> All -> All #stimes :: Integral b => b -> All -> All # Since: base-4.9.0.0 Instance detailsDefined in Data.Semigroup.Internal Methods(<>) :: Any -> Any -> Any #stimes :: Integral b => b -> Any -> Any # Since: base-4.9.0.0 Instance detailsDefined in Data.Void Methods(<>) :: Void -> Void -> Void #stimes :: Integral b => b -> Void -> Void # Instance detailsDefined in Data.ByteString.Builder.Internal Methodsstimes :: Integral b => b -> Builder -> Builder # Instance detailsDefined in Data.ByteString.Internal Methodsstimes :: Integral b => b -> ByteString -> ByteString # Instance detailsDefined in Data.ByteString.Lazy.Internal Methodsstimes :: Integral b => b -> ByteString -> ByteString # Instance detailsDefined in Data.ByteString.Short.Internal Methodsstimes :: Integral b => b -> ShortByteString -> ShortByteString # Since: containers-0.5.7 Instance detailsDefined in Data.IntSet.Internal Methods(<>) :: IntSet -> IntSet -> IntSet #stimes :: Integral b => b -> IntSet -> IntSet # Instance detailsDefined in Data.Array.Byte Methodsstimes :: Integral b => b -> ByteArray -> ByteArray # Since: base-4.9.0.0 Instance detailsDefined in GHC.Base Methodsstimes :: Integral b => b -> Ordering -> Ordering # Source # Instance detailsDefined in Hedgehog.Internal.Property Methods(<>) :: Cover -> Cover -> Cover #stimes :: Integral b => b -> Cover -> Cover # Source # Instance detailsDefined in Hedgehog.Internal.Property Methodsstimes :: Integral b => b -> CoverCount -> CoverCount # Source # Instance detailsDefined in Hedgehog.Internal.Property Methodsstimes :: Integral b => b -> GroupName -> GroupName # Source # Instance detailsDefined in Hedgehog.Internal.Property Methodsstimes :: Integral b => b -> Journal -> Journal # Source # Instance detailsDefined in Hedgehog.Internal.Property Methodsstimes :: Integral b => b -> LabelName -> LabelName # Source # Instance detailsDefined in Hedgehog.Internal.Property Methodsstimes :: Integral b => b -> PropertyName -> PropertyName # Source # Instance detailsDefined in Hedgehog.Internal.Report Methods(<>) :: Style -> Style -> Style #stimes :: Integral b => b -> Style -> Style # Source # Instance detailsDefined in Hedgehog.Internal.Report Methodsstimes :: Integral b => b -> Summary -> Summary # Instance detailsDefined in Text.PrettyPrint.HughesPJ Methods(<>) :: Doc -> Doc -> Doc #stimes :: Integral b => b -> Doc -> Doc # Since: base-4.9.0.0 Instance detailsDefined in GHC.Base Methods(<>) :: () -> () -> () #sconcat :: NonEmpty () -> () #stimes :: Integral b => b -> () -> () # Only defined by async for base >= 4.9Since: async-2.1.0 Instance detailsDefined in Control.Concurrent.Async Methods(<>) :: Concurrently a -> Concurrently a -> Concurrently a #stimes :: Integral b => b -> Concurrently a -> Concurrently a # Bits a => Semigroup (And a) Since: base-4.16 Instance detailsDefined in Data.Bits Methods(<>) :: And a -> And a -> And a #sconcat :: NonEmpty (And a) -> And a #stimes :: Integral b => b -> And a -> And a # FiniteBits a => Semigroup (Iff a) This constraint is arguably too strong.

In other words, it evaluates the first argument a to weak head normal form (WHNF). seq is usually introduced to improve performance by avoiding unneeded laziness. A note on evaluation order: the expression seq a b does not guarantee that a will be evaluated before b. The only guarantee given by seq is that the both a and b will be evaluated before seq returns a value. In particular, this means that b may be evaluated before a. If you need to guarantee a specific order of evaluation, you must use the function pseq from the "parallel" package. zip :: [a] -> [b] -> [(a, b)] # $$\mathcal{O}(\min(m,n))$$. zip takes two lists and returns a list of corresponding pairs. >>> zip [1, 2] ['a', 'b'] [(1,'a'),(2,'b')]  If one input list is shorter than the other, excess elements of the longer list are discarded, even if one of the lists is infinite: >>> zip [1] ['a', 'b'] [(1,'a')] >>> zip [1, 2] ['a'] [(1,'a')] >>> zip [] [1..] [] >>> zip [1..] [] []  zip is right-lazy: >>> zip [] undefined [] >>> zip undefined [] *** Exception: Prelude.undefined ...  zip is capable of list fusion, but it is restricted to its first list argument and its resulting list. fst :: (a, b) -> a # Extract the first component of a pair. snd :: (a, b) -> b # Extract the second component of a pair. otherwise is defined as the value True. It helps to make guards more readable. eg.  f x | x < 0 = ... | otherwise = ... ($) :: forall (r :: RuntimeRep) a (b :: TYPE r). (a -> b) -> a -> b infixr 0 #

Application operator. This operator is redundant, since ordinary application (f x) means the same as (f $x). However, $ has low, right-associative binding precedence, so it sometimes allows parentheses to be omitted; for example:

f $g$ h x  =  f (g (h x))

It is also useful in higher-order situations, such as map ($0) xs, or zipWith ($) fs xs.

Note that ($) is levity-polymorphic in its result type, so that foo$ True where foo :: Bool -> Int# is well-typed.

fromIntegral :: (Integral a, Num b) => a -> b #

general coercion from integral types

realToFrac :: (Real a, Fractional b) => a -> b #

general coercion to fractional types

class Bounded a where #

The Bounded class is used to name the upper and lower limits of a type. Ord is not a superclass of Bounded since types that are not totally ordered may also have upper and lower bounds.

The Bounded class may be derived for any enumeration type; minBound is the first constructor listed in the data declaration and maxBound is the last. Bounded may also be derived for single-constructor datatypes whose constituent types are in Bounded.

class Enum a where #

Class Enum defines operations on sequentially ordered types.

The enumFrom... methods are used in Haskell's translation of arithmetic sequences.

Instances of Enum may be derived for any enumeration type (types whose constructors have no fields). The nullary constructors are assumed to be numbered left-to-right by fromEnum from 0 through n-1. See Chapter 10 of the Haskell Report for more details.

For any type that is an instance of class Bounded as well as Enum, the following should hold:

• The calls succ maxBound and pred minBound should result in a runtime error.
• fromEnum and toEnum should give a runtime error if the result value is not representable in the result type. For example, toEnum 7 :: Bool is an error.
• enumFrom and enumFromThen should be defined with an implicit bound, thus:
   enumFrom     x   = enumFromTo     x maxBound
enumFromThen x y = enumFromThenTo x y bound
where
| otherwise                = minBound

Methods

succ :: a -> a #

the successor of a value. For numeric types, succ adds 1.

pred :: a -> a #

the predecessor of a value. For numeric types, pred subtracts 1.

toEnum :: Int -> a #

Convert from an Int.

fromEnum :: a -> Int #

Convert to an Int. It is implementation-dependent what fromEnum returns when applied to a value that is too large to fit in an Int.

enumFrom :: a -> [a] #

Used in Haskell's translation of [n..] with [n..] = enumFrom n, a possible implementation being enumFrom n = n : enumFrom (succ n). For example:

• enumFrom 4 :: [Integer] = [4,5,6,7,...]
• enumFrom 6 :: [Int] = [6,7,8,9,...,maxBound :: Int]

enumFromThen :: a -> a -> [a] #

Used in Haskell's translation of [n,n'..] with [n,n'..] = enumFromThen n n', a possible implementation being enumFromThen n n' = n : n' : worker (f x) (f x n'), worker s v = v : worker s (s v), x = fromEnum n' - fromEnum n and f n y | n > 0 = f (n - 1) (succ y) | n < 0 = f (n + 1) (pred y) | otherwise = y For example:

• enumFromThen 4 6 :: [Integer] = [4,6,8,10...]
• enumFromThen 6 2 :: [Int] = [6,2,-2,-6,...,minBound :: Int]

enumFromTo :: a -> a -> [a] #

Used in Haskell's translation of [n..m] with [n..m] = enumFromTo n m, a possible implementation being enumFromTo n m | n <= m = n : enumFromTo (succ n) m | otherwise = []. For example:

• enumFromTo 6 10 :: [Int] = [6,7,8,9,10]
• enumFromTo 42 1 :: [Integer] = []

enumFromThenTo :: a -> a -> a -> [a] #

Used in Haskell's translation of [n,n'..m] with [n,n'..m] = enumFromThenTo n n' m, a possible implementation being enumFromThenTo n n' m = worker (f x) (c x) n m, x = fromEnum n' - fromEnum n, c x = bool (>=) ((x 0) f n y | n > 0 = f (n - 1) (succ y) | n < 0 = f (n + 1) (pred y) | otherwise = y and worker s c v m | c v m = v : worker s c (s v) m | otherwise = [] For example:

• enumFromThenTo 4 2 -6 :: [Integer] = [4,2,0,-2,-4,-6]
• enumFromThenTo 6 8 2 :: [Int] = []

For example, when enumerating values of resolution 10^-3 of type Milli = Fixed E3, succ (0.000 :: Milli) == 1.001 and likewise pred (0.000 :: Milli) == -0.001 In other words, succ and pred increment and decrement a fixed-precision value by the least amount such that the value's resolution is unchanged. For example, 10^-12 is the smallest (positive) amount that can be added to a value of type Pico = Fixed E12 without changing its resolution, and so succ (0.000000000000 :: Pico) == 0.000000000001 and similarly pred (0.000000000000 :: Pico) == -0.000000000001 This is worth bearing in mind when defining Fixed arithmetic sequences. In particular, you may be forgiven for thinking the sequence [1..10] :: [Pico] evaluates to [1, 2, 3, 4, 5, 6, 7, 8, 9, 10] :: [Pico].However, this is not true. On the contrary, similarly to the above implementations of succ and pred, enumFromTo :: Pico -> Pico -> [Pico] has a "step size" of 10^-12. Hence, the list [1..10] :: [Pico] has the form [1.000000000000, 1.00000000001, 1.00000000002, ..., 10.000000000000] and contains 9 * 10^12 + 1 values.Since: base-2.1 Instance detailsDefined in Data.Fixed Methodssucc :: Fixed a -> Fixed a #pred :: Fixed a -> Fixed a #toEnum :: Int -> Fixed a #fromEnum :: Fixed a -> Int #enumFrom :: Fixed a -> [Fixed a] #enumFromThen :: Fixed a -> Fixed a -> [Fixed a] #enumFromTo :: Fixed a -> Fixed a -> [Fixed a] #enumFromThenTo :: Fixed a -> Fixed a -> Fixed a -> [Fixed a] # Enum (Proxy s) Since: base-4.7.0.0 Instance detailsDefined in Data.Proxy Methodssucc :: Proxy s -> Proxy s #pred :: Proxy s -> Proxy s #toEnum :: Int -> Proxy s #fromEnum :: Proxy s -> Int #enumFrom :: Proxy s -> [Proxy s] #enumFromThen :: Proxy s -> Proxy s -> [Proxy s] #enumFromTo :: Proxy s -> Proxy s -> [Proxy s] #enumFromThenTo :: Proxy s -> Proxy s -> Proxy s -> [Proxy s] # Enum a => Enum (Const a b) Since: base-4.9.0.0 Instance detailsDefined in Data.Functor.Const Methodssucc :: Const a b -> Const a b #pred :: Const a b -> Const a b #toEnum :: Int -> Const a b #fromEnum :: Const a b -> Int #enumFrom :: Const a b -> [Const a b] #enumFromThen :: Const a b -> Const a b -> [Const a b] #enumFromTo :: Const a b -> Const a b -> [Const a b] #enumFromThenTo :: Const a b -> Const a b -> Const a b -> [Const a b] # Enum (f a) => Enum (Ap f a) Since: base-4.12.0.0 Instance detailsDefined in Data.Monoid Methodssucc :: Ap f a -> Ap f a #pred :: Ap f a -> Ap f a #toEnum :: Int -> Ap f a #fromEnum :: Ap f a -> Int #enumFrom :: Ap f a -> [Ap f a] #enumFromThen :: Ap f a -> Ap f a -> [Ap f a] #enumFromTo :: Ap f a -> Ap f a -> [Ap f a] #enumFromThenTo :: Ap f a -> Ap f a -> Ap f a -> [Ap f a] # Enum (f a) => Enum (Alt f a) Since: base-4.8.0.0 Instance detailsDefined in Data.Semigroup.Internal Methodssucc :: Alt f a -> Alt f a #pred :: Alt f a -> Alt f a #toEnum :: Int -> Alt f a #fromEnum :: Alt f a -> Int #enumFrom :: Alt f a -> [Alt f a] #enumFromThen :: Alt f a -> Alt f a -> [Alt f a] #enumFromTo :: Alt f a -> Alt f a -> [Alt f a] #enumFromThenTo :: Alt f a -> Alt f a -> Alt f a -> [Alt f a] # Enum a => Enum (Tagged s a) Instance detailsDefined in Data.Tagged Methodssucc :: Tagged s a -> Tagged s a #pred :: Tagged s a -> Tagged s a #toEnum :: Int -> Tagged s a #fromEnum :: Tagged s a -> Int #enumFrom :: Tagged s a -> [Tagged s a] #enumFromThen :: Tagged s a -> Tagged s a -> [Tagged s a] #enumFromTo :: Tagged s a -> Tagged s a -> [Tagged s a] #enumFromThenTo :: Tagged s a -> Tagged s a -> Tagged s a -> [Tagged s a] #

class Eq a where #

The Eq class defines equality (==) and inequality (/=). All the basic datatypes exported by the Prelude are instances of Eq, and Eq may be derived for any datatype whose constituents are also instances of Eq.

The Haskell Report defines no laws for Eq. However, instances are encouraged to follow these properties:

Reflexivity
x == x = True
Symmetry
x == y = y == x
Transitivity
if x == y && y == z = True, then x == z = True
Extensionality
if x == y = True and f is a function whose return type is an instance of Eq, then f x == f y = True
Negation
x /= y = not (x == y)

Minimal complete definition: either == or /=.
