Description

@deven

Feature gate: #![feature(trim_prefix_suffix)]

This is a tracking issue for adding trim_prefix and trim_suffix methods to str that remove at most one occurrence of a specified prefix or suffix while always returning a string slice (rather than Option<&str>), enabling easy method chaining.1

Public API

impl str {
    pub fn trim_prefix<P>(&self, prefix: P) -> &str
    where
        P: Pattern;

    pub fn trim_suffix<P>(&self, suffix: P) -> &str
    where
        P: Pattern,
        for<'a> P::Searcher<'a>: ReverseSearcher<'a>;
}
