Trait Arena 

pub trait Arena<T>: UnsafeArena<T> {
    // Required methods
    fn get(&self, ptr: &Self::Ptr) -> Option<&T>;
    fn get_mut(&mut self, ptr: &Self::Ptr) -> Option<&mut T>;
    fn remove(&mut self, ptr: &Self::Ptr) -> Option<T>;
}

Memory-safe homogeneous memory arena types.

Required Methods

fn get(&self, ptr: &Self::Ptr) -> Option<&T>

Get a reference to a contained value.

fn get_mut(&mut self, ptr: &Self::Ptr) -> Option<&mut T>

Get a mutable reference to a contained value.

fn remove(&mut self, ptr: &Self::Ptr) -> Option<T>

Remove a value from the arena.

Returns the removed value.
