Trait SizableContainer

pub trait SizableContainer {
    // Required methods
    fn at_capacity(&self) -> bool;
    fn ensure_capacity(&mut self, stash: &mut Option<Self>)
       where Self: Sized;
}

A container that can be sized and reveals its capacity.

Required Methods

fn at_capacity(&self) -> bool

Indicates that the container is “full” and should be shipped.

fn ensure_capacity(&mut self, stash: &mut Option<Self>)

where Self: Sized,

Restores self to its desired capacity, if it has one.

The stash argument is available, and may have the intended capacity. However, it may be non-empty, and may be of the wrong capacity. The method should guard against these cases.

Assume that the stash is in an undefined state, and properly clear it before re-using it.
