Required Methods§
sourcefn retain_mut<F>(&mut self, f: F)
👎Deprecated: Rust 1.61 has included retain_mut directly
fn retain_mut<F>(&mut self, f: F)
Retains only the elements specified by the predicate, passing a mutable reference to it.
In other words, remove all elements e
such that f(&mut e)
returns false
.
This method operates in place, visiting each element exactly once in the
original order, and preserves the order of the retained elements.

This trait is not object safe.
