Extension methods for ASCII-subset only operations on string slices

Required Methods

fn to_ascii_upper(&self) -> String

Makes a copy of the string in ASCII upper case: ASCII letters 'a' to 'z' are mapped to 'A' to 'Z', but non-ASCII letters are unchanged.

fn to_ascii_lower(&self) -> String

Makes a copy of the string in ASCII lower case: ASCII letters 'A' to 'Z' are mapped to 'a' to 'z', but non-ASCII letters are unchanged.

fn eq_ignore_ascii_case(&self, other: &str) -> bool

Check that two strings are an ASCII case-insensitive match. Same as to_ascii_lower(a) == to_ascii_lower(b), but without allocating and copying temporary strings.
