IsIndexContainer trait for containers holding indices

Required Methods

fn reserve(&mut self, n: usize)

Should reserve space for n more elements

fn ensure_supported(&mut self, x: usize)

Should ensure that given number can be supported

fn len(&self) -> usize

Should return the number of elements

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

Should return the element at index

fn set(&mut self, index: usize, value: usize)

Should overwrite the element at index with value

fn push(&mut self, value: usize)

Should push value to the end of the container

fn iter(&self) -> IsIndexContainerIterator<'_, Self>

Should return an iterator over the values

Provided Methods

fn with_capacity(n: usize) -> Self

Creates a new object with the given capacity

fn with_support_for(x: usize) -> Self

Creates a new object that can support the given number

fn with_capacity_and_support_for(n: usize, x: usize) -> Self

Creates a new object with the given capacity and support for the given number

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.
