Required Methods

fn trim_start_matches<F>(&self, f: F) -> &[T]

where F: FnMut(&T) -> bool,

Returns a slice with all matching elements from the start of the slice removed.

fn trim_end_matches<F>(&self, f: F) -> &[T]

where F: FnMut(&T) -> bool,

Returns a slice with all matching elements from the end of the slice removed.

fn group_by_key<K, F>(&self, f: F) -> GroupByKey<'_, T, F>

where F: FnMut(&T) -> K, K: PartialEq,

Split a slice into consecutive runs with the same key and yield for each such run the key and the slice of elements with that key.
