Trait RandomAccessSequence

pub trait RandomAccessSequence<T: Copy> {
    // Required methods
    fn len(&self) -> usize;
    unsafe fn get_unchecked(&self, index: usize) -> T;

    // Provided methods
    fn is_empty(&self) -> bool { ... }
    fn get(&self, index: usize) -> T { ... }
}

A trait for a collection that allows indexed access by value. This trait is used to abstract over different types of collections - scalar slices, slices of packed field elements including subranges of collections.

Required Methods

fn len(&self) -> usize

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

Returns a copy of the element at the given index.

Safety

The caller must ensure that the index < self.len().

Provided Methods

fn is_empty(&self) -> bool

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