stride

Crates.io Version Docs.rs Latest Build Status

A strided slice type.

Getting started

This crate provides a slice-like Stride<T, S> type where elements are spaced a constant S elements in memory.

For example, given an underlying slice &[1, 2, 3, 4, 5, 6], the elements &[1, 3, 5] are a strided slice with a stride of 2. This crate makes use of const generics to provide the stride value S at compile time so that there is no runtime memory overhead to strided slices; Stride takes up the same amount of space as a slice.

Many slice-like operations are implemented for Stride including iteration and indexing. Method names are similar to those of the slice type.

use stride::Stride;

// The underlying data.
let data = &mut [1, 2, 7, 4, 5, 6];

// Create a strided slice with a stride of `2` referring to
// elements `1`, `7`, and `5`.
let stride = Stride::<_, 2>::new_mut(data);

assert_eq!(stride.len(), 3);

// We can use indexing to view values ..
assert_eq!(stride[0], 1);
assert_eq!(stride[1..3], &[7, 5]);

// .. or modify them.
stride[1] = 3;
assert_eq!(stride, &[1, 3, 5]);

assert_eq!(data, &[1, 2, 3, 4, 5, 6]);
