Prisms

_Base64 :: Prism' Text Text Source #

A Prism into the Base64 encoding of a Text value.

>>> _Base64 # "Sun"
"U3Vu"

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

_Base64Url :: Prism' Text Text Source #

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

>>> _Base64Url # "Sun"
"U3Vu"

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

_Base64Unpadded :: Prism' Text Text Source #

A Prism into the unpadded Base64 encoding of a Text 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.

>>> _Base64Unpadded # "Sun"
"U3Vu"

>>> "U3Vu" ^? _Base64Unpadded
Just "Sun"

_Base64UrlUnpadded :: Prism' Text Text Source #

A Prism into the Base64-url encoding of a Text 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' Text Text Source #

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

_Note:_ This is not a lawful Iso.

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

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

_Base64UrlLenient :: Iso' Text Text Source #

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

_Note:_ This is not a lawful Iso.

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

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