Synopsis

>>> :set -XScopedTypeVariables -XTypeFamilies -XKindSignatures -XDataKinds

Represents value level (single) annotation. @since 0.2.0.0

Contraint for "r-" annotations.

Since: 0.3.0.0

type Algorithm nm alg = AlgNm nm ~ alg Source #

Contraint for algorithm name.

Since: 0.3.0.0

type family AlgNm (encnm :: Symbol) :: Symbol where ... Source #

Converts encoding name to algorithm name, this assumes the ":" delimiter expected by this library.

This allows working with open encoding definitions such as "r-ban" or "r-bool"

>>> :kind! AlgNm "enc-B64"
...
= "enc-B64"

>>> :kind! AlgNm "r-ban:999-99-9999"
...
= "r-ban"

Since: 0.3.0.0

Equations

AlgNm encnm = TakeUntil encnm ":"

type family AlgNmMap (nms :: [Symbol]) :: [Symbol] where ... Source #

Since: 0.3.0.0

Equations

AlgNmMap (x ': xs) = AlgNm x ': AlgNmMap xs

type family IsR (s :: Symbol) :: Bool where ... Source #
