Trait RandPop

pub trait RandPop: Sized {
    type Item;

    // Required method
    fn rand_pop<R: Rng>(&mut self, rng: &mut R) -> Option<Self::Item>;

    // Provided method
    fn rand_iter<R: Rng>(self, rng: &mut R) -> RandIter<'_, Self, R>  { ... }
}

Interface for randomly removing elements from a container.

Required Associated Types

type Item

Type of the item that’s removed from the container.

Required Methods

fn rand_pop<R: Rng>(&mut self, rng: &mut R) -> Option<Self::Item>

Randomly removes an item from the container; does not necessarily preserve order.

Provided Methods

fn rand_iter<R: Rng>(self, rng: &mut R) -> RandIter<'_, Self, R>

Randomly iterates through the items in this container, consuming the container.

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.
