Data.Time.Clock.Duration.Types

This module exports internally used type classes and data types. You can extend this package's functionality by utilizing them.

Type classes

class AbsoluteDuration a where

The AbsoluteDuration class provides how to convert the given Time into a specific unit of time. An instance should represent a quantity with the dimension of T.

42 seconds in DiffTime (seconds):

>>> [t| 42s |] :: DiffTime
42s

42 seconds in CUSeconds (microseconds):

>>> [t| 42s |] :: CUSeconds
42000000

Methods

toAbsoluteDuration :: Time -> a

Instances

AbsoluteDuration CUSeconds

Caution: the fractional part will be rounded.

Defined in Data.Time.Clock.Duration.Types

AbsoluteDuration DiffTime

Defined in Data.Time.Clock.Duration.Types

Methods

toAbsoluteDuration :: Time -> DiffTime

class RelativeDuration a where

The RelativeDuration class represents how to calculate how long the given Time is when measured in a specific unit of time. An instance should represent a quantity with the dimension of 1.

42 minutes in seconds:

>>> [s| 42m |] :: Int
2520

3 seconds in microseconds:

>>> [µs| 3s |] :: Int
3000000
