Data.ByteString.Base32.Lens

This module contains Prism's for Base32-encoding and decoding ByteString values.

Prisms

_Base32 :: Prism' ByteString ByteString

A Prism' into the Base32 encoding of a ByteString value

>>> _Base32 # "Sun"
"KN2W4==="

>>> "KN2W4===" ^? _Base32
Just "Sun"

_Base32Unpadded :: Prism' ByteString ByteString

A Prism' into the Base32 encoding of a ByteString 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.

>>> _Base32Unpadded # "Sun"
"KN2W4"

>>> "KN2W4" ^? _Base32Unpadded
Just "Sun"

_Base32Hex :: Prism' ByteString ByteString

A Prism' into the Base32hex encoding of a ByteString value

>>> _Base32Hex # "Sun"
"ADQMS==="

>>> "ADQMS===" ^? _Base32Hex
Just "Sun"

_Base32HexUnpadded :: Prism' ByteString ByteString

A Prism' into the Base32hex encoding of a ByteString 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.

>>> _Base32HexUnpadded # "Sun"
"ADQMS"

>>> "ADQMS" ^? _Base32HexUnpadded
Just "Sun"
