Data.Text.Encoding.Base64.Lens

This module contains the AsBase64 and AsBase64Unpadded instances for Text, which defined to be the collection of Prisms defining the RFC 4648 specification for the padded and unpadded Base64 encoding format.

These typeclasses are re-exported for convenience

Documentation

class AsBase64 s where

If a particular type s has a base64 representation for any of its focii, this class provides the optical interface for satisfying the padded base64 spec in RFC 4648

Associated Types

type Base64 s

Methods

_Base64 :: Prism' s (Base64 s)

A prism into a base64-encoded focus of some type

Examples:

>>> _Base64 @Text # "Sun"
"UV3u"
   --
>>> "PDw/Pz8+Pg==" ^? _Base64
Just "<<???>>"

_Base64Url :: Prism' s (Base64 s)

A prism into the base64url-encoded focus of some type

Examples:

>>> _Base64Url @Text # "Sun"
"UV3u"

>>> "PDw_Pz8-Pg==" ^? _Base64Url
Just "<<???>>"
