Trait IArena 

pub trait IArena<T> {
    // Required methods
    fn alloc(&mut self, value: T) -> Idx<T>;
    fn free(&mut self, id: Idx<T>) -> T;
    fn get(&self, id: Idx<T>) -> &T;
    fn get_mut(&mut self, id: Idx<T>) -> &mut T;
}

Arena for allocating and managing items.

Required Methods

fn alloc(&mut self, value: T) -> Idx<T>

Allocate a new item, returning its index.

fn free(&mut self, id: Idx<T>) -> T

Free an item, returning it.

Panics

Panics if the index is invalid or already freed.

fn get(&self, id: Idx<T>) -> &T

Get a reference to an item.

Panics

Panics if the index is invalid or freed.

fn get_mut(&mut self, id: Idx<T>) -> &mut T

Get a mutable reference to an item.

Panics

Panics if the index is invalid or freed.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
