Public predicates

parse/2

Parses the Base64 data from the given source (atom(Atom), chars(List), codes(List), stream(Stream), or file(Path) into a list of bytes.

Compilation flags:

static

Template:

parse(Source,Bytes)

Mode and number of proofs:

parse(++compound,--list(byte)) - one_or_error

Exceptions:

Source is a variable:

instantiation_error

Source is neither a variable nor a valid Base64 source term:

domain_error(base64_source,Source)

Source contains Base64 data with characters outside the Base64 alphabet:

representation_error(base64)

---

generate/2

Generates Base64 in the representation specified in the first argument (atom(Atom), chars(List), codes(List), stream(Stream), or file(Path) for the list of bytes in the second argument.

Compilation flags:

static

Template:

generate(Sink,Bytes)

Mode and number of proofs:

generate(+compound,+list(byte)) - one_or_error

Exceptions:

Sink is a variable:

instantiation_error

Sink is neither a variable nor a valid Base64 sink term:

domain_error(base64_sink,Sink)
