Prisms

_Base64 :: Prism' ShortText ShortText Source #

A Prism into the Base64 encoding of a ShortText value.

>>> _Base64 # "Sun"
"U3Vu"

>>> "U3Vu" ^? _Base64
Just "Sun"

_Base64Url :: Prism' ShortText ShortText Source #

A Prism into the Base64-url encoding of a ShortText value.

>>> _Base64Url # "Sun"
"U3Vu"

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

_Base64UrlUnpadded :: Prism' ShortText ShortText Source #

A Prism into the Base64-url encoding of a ShortText value.

Please note that unpadded variants should only be used when assumptions about the data can be made. In particular, if the length of the input is divisible by 3, then this is a safe function to call.

>>> _Base64UrlUnpadded # "<<??>>"
"PDw_Pz4-"

>>> "PDw_Pz4-" ^? _Base64UrlUnpadded
Just "<<??>>"

_Base64Lenient :: Iso' ShortText ShortText Source #

An Iso' into the Base64 encoding of a ShortText value using lenient decoding.

_Note:_ This is not a lawful Iso in general. Please take care!

>>> _Base64Lenient # "Sun"
"U3Vu"

>>> "U3Vu" ^. _Base64Lenient
"Sun"

_Base64UrlLenient :: Iso' ShortText ShortText Source #

An Iso' into the Base64url encoding of a ShortText value using lenient decoding.

_Note:_ This is not a lawful Iso in general. Please take care!

>>> _Base64UrlLenient # "<<??>>"
"PDw_Pz4-"

>>> "PDw_Pz4-" ^. _Base64UrlLenient
"<<??>>"
