Base16-lens

This package provides optics and convenient pattern synonyms for the base16 library.

Patterns

The pattern synonyms provided in this library are:

pattern Hex :: ByteString -> ByteString
-- and
pattern Hex :: Text -> Text

These provide a convenient high level interface for passing Base16 encoded values.

Optics

Prisms for encoding and decoding Text and ByteString values are given as part of the library:

_Hex :: Prism' ByteString ByteString

-- and

_Hex:: Prism' Text Text

If a particular structure has a Lens into some Text or ByteString value they might want to encode (or decode), then composing such a Lens with these Prisms yields an affine Traversal, resulting in a structure which has the focus of its Lens encoded as or decoded from Base16.
