Encoders

encB64B :: Applicative f => Encoding f "enc-B64" "enc-B64" c ByteString

Since: 0.3.0.0

encB64BL :: Applicative f => Encoding f "enc-B64" "enc-B64" c ByteString

Since: 0.3.0.0

endB64T :: Applicative f => Encoding f "enc-B64" "enc-B64" c Text

This function will likely be removed in future versions (performance concerns)

Decoders

decB64B :: (UnexpectedDecodeErr f, Applicative f) => Decoding f "enc-B64" "enc-B64" c ByteString

Effectful decoding for corruption detection. This protocol is used, for example, in emails. It is a well known encoding and hackers will have no problem making undetectable changes, but error handling at this stage could verify that email was corrupted.

Since: 0.3.0.0

decB64BL :: (UnexpectedDecodeErr f, Applicative f) => Decoding f "enc-B64" "enc-B64" c ByteString

Warning: This method was not optimized for performance.

Validation

Orphan instances

EncodingSuperset "enc-B64"

This is not precise, actually Base 64 uses a subset of ASCII and that would require a new definition "r-B64".

This instance likely to be changed / corrected in the future if "r-B64" is defined.

>>> let tstB64 = encodeAll . toEncoding () $ "Hello World" :: Enc '["enc-B64"] () B.ByteString
>>> displ (_encodesInto @"r-ASCII" $ tstB64)
"Enc '[r-ASCII,enc-B64] () (ByteString SGVsbG8gV29ybGQ=)"

>>> displ (_encodesInto @"r-UTF8" $ tstB64)
"Enc '[r-UTF8,enc-B64] () (ByteString SGVsbG8gV29ybGQ=)"
