source§fn test<'i>(&self, input: &'i [u8]) -> Option<(&'i [u8], &'i [u8])>
fn test<'i>(&self, input: &'i [u8]) -> Option<(&'i [u8], &'i [u8])>
Tests the pattern against the input slice. If the pattern matches, the matching part is
returned along with what is left of the input. Returns
None if the pattern does not matchsource§fn or<P>(self, other: P) -> Or<Self, P>where
