Show (Size ctx)

Defined in DeBruijn.Internal.Size

Methods

showsPrec :: Int -> Size ctx -> ShowS

show :: Size ctx -> String

Eq (Size ctx)

Defined in DeBruijn.Internal.Size

Methods

(==) :: Size ctx -> Size ctx -> Bool

(/=) :: Size ctx -> Size ctx -> Bool

Ord (Size ctx)

Defined in DeBruijn.Internal.Size

Methods

compare :: Size ctx -> Size ctx -> Ordering

(<) :: Size ctx -> Size ctx -> Bool

(<=) :: Size ctx -> Size ctx -> Bool

(>) :: Size ctx -> Size ctx -> Bool

(>=) :: Size ctx -> Size ctx -> Bool

max :: Size ctx -> Size ctx -> Size ctx

min :: Size ctx -> Size ctx -> Size ctx

unSS :: Size (S ctx) -> Size ctx

Unapply SS. Occasionally more useful than pattern matching.

sizeToInt :: Size ctx -> Int

Convert Size to 'Int.
