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.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
