Classy Prisms

Description

This module contains the AsBase64 instance for Text, which is defined to be the collection of Prisms defining the RFC 4648 specification for the Base64 encoding format.

In order to expose this file, you must build the package with '-foptics' enabled.

Synopsis

class AsBase64 s where
- type Base64 s
- _Base64 :: Prism' s (Base64 s)
- _Base64Url :: Prism' s (Base64 s)
class AsBase64Unpadded s where
- type Base64Unpadded s
- _Base64Unpadded :: Prism' s (Base64Unpadded s)
- _Base64UrlUnpadded :: Prism' s (Base64Unpadded s)

Classy Prisms

class AsBase64 s where Source #

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 Source #

Methods

_Base64 :: Prism' s (Base64 s) Source #

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) Source #

A prism into the base64url-encoded focus of some type

Examples:

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

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