Public predicates

.. index:: parse/2 .. _base64url/0::parse/2:

parse/2 ^^^^^^^^^^^

Parses the Base64URL data from the given source (atom(Atom), chars(List), or codes(List) into a URL (using the same format as the source).

| Compilation flags: | static

| Template: | parse(Source,URL) | Mode and number of proofs: | parse(++compound,--types([atom,chars,codes])) - one_or_error

| Exceptions: | Source is a variable: | instantiation_error | Source is neither a variable nor a valid Base64 source term: | domain_error(base64url_source,Source) | Source contains Base64URL data with characters outside the Base64URL alphabet: | representation_error(base64)

---

.. index:: generate/2 .. _base64url/0::generate/2:

generate/2 ^^^^^^^^^^^^^^

Generates Base64URL data in the representation specified in the first argument (atom(Atom), chars(List), or codes(List) for the given URL (given in the same format as the sink).

| Compilation flags: | static

| Template: | generate(Sink,URL) | Mode and number of proofs: | generate(+compound,+types([atom,chars,codes])) - one_or_error

| Exceptions: | Sink is a variable: | instantiation_error | Sink is neither a variable nor a valid Base64 sink term: | domain_error(base64url_sink,Sink)
