Trait GetEntry

pub trait GetEntry<'a>: GetMut {
    type Occupied: OccupiedEntry<'a, Self>;
    type Vacant: VacantEntry<'a, Self>;

    // Required method
    fn entry(&'a mut self, key: Self::Key) -> Entry<'a, Self>;
}

A trait for getting an entry at a given key.

Required Associated Types

type Occupied: OccupiedEntry<'a, Self>

The type of an occupied entry.

type Vacant: VacantEntry<'a, Self>

The type of a vacant entry.

Required Methods

fn entry(&'a mut self, key: Self::Key) -> Entry<'a, Self>

Gets the entry.

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.
