pub trait OffsetContainer<T>: Default + Extend<T> {
    // Required methods
    fn push(&mut self, item: T);
    fn index(&self, index: usize) -> T;
    fn clear(&mut self);

    fn is_empty(&self) -> bool { ... }
}

A container to store offsets.

Required Methods

fn push(&mut self, item: T)

Accepts a newly pushed element.

fn index(&self, index: usize) -> T

Lookup an index. May panic for invalid indexes.

fn clear(&mut self)

Clear all contents.

fn len(&self) -> usize

Returns the number of elements.

fn reserve(&mut self, additional: usize)

Reserve space for additional elements.

fn heap_size<F: FnMut(usize, usize)>(&self, callback: F)

Heap size, size - capacity

Provided Methods

fn is_empty(&self) -> bool

Returns true if empty.
