Trait RetainMutUnordered 

pub trait RetainMutUnordered<T> {
    // Required methods
    fn truncate(&mut self, val: usize);
    fn as_slice_mut(&mut self) -> &mut [T];

    // Provided method
    fn retain_mut_unordered<F>(&mut self, f: F)
       where F: FnMut(&mut T) -> bool { ... }
}

Retain only elements that satisfy the predicate. May rearrange elements in the process.

Required Methods

fn truncate(&mut self, val: usize)

fn as_slice_mut(&mut self) -> &mut [T]

Provided Methods

fn retain_mut_unordered<F>(&mut self, f: F)

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

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.
