Data.Text.Encoding.Base64.Lens

This module contains Prisms Base64-encoding and decoding Text values.

Prisms

_Base64 :: Prism' Text Text

A Prism into the Base64 encoding of a Text value.

>>> _Base64 # "Sun"
"U3Vu"

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

_Base64Url :: Prism' Text Text

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

>>> _Base64Url # "Sun"
"U3Vu"

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

_Base64Unpadded :: Prism' Text Text

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

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 "<<??>>"
