API details and source

The implementation source contains the complete declarations and implementation notes. The table below lists canonical Gossamer call signatures; every item name links directly to its implementation file.

Item	Canonical signature or declaration	Description
decode_surrogate_pair	fn decode_surrogate_pair(high: char, low: char) -> Result<char, errors::Error>	Decodes a high+low surrogate pair to a char.
decode_to_string	fn decode_to_string(units: Vec<u16>) -> Result<String, errors::Error>	Decodes a []u16 to String.
encode_string	fn encode_string(text: String) -> Vec<u16>	Encodes a String directly to Vec.
is_surrogate	fn is_surrogate(rune: char) -> bool	True iff r falls in the surrogate range U+D800..U+DFFF.
rune_len	fn rune_len(rune: char) -> i64	Number of UTF-16 code units needed to encode r (1 or 2).
