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)

---

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:
