Crate collect_slice [−] [src]
Collect an iterator into a slice.
Rust comes with the
Iterator::collect method for collecting an iterator's items into
Vec or any other type that implements
FromIterator, but there's
no way to collect items into a stack-allocated array without manually looping over the
iterator. This crates provides an alternative with
collect_slice methods that
collect an iterator's items into a mutable slice (of a stack-allocated array or
The trait is automatically implemented for any type that implements
use collect_slice::CollectSlice; let mut orig = [0; 8]; (0..8).map(|i| i * 2).collect_slice_checked(&mut orig[..]); assert_eq!(orig, [0, 2, 4, 6, 8, 10, 12, 14]); let mut buf = [42; 8]; orig.iter() .map(|&x| x + 10) .collect_slice_checked(&mut buf[..]); assert_eq!(buf, [10, 12, 14, 16, 18, 20, 22, 24]);
This crate can be used through cargo by adding it as a dependency in
[dependencies] collect_slice = "^1.2.0"
and importing it in the crate root:
extern crate collect_slice;
The provided methods can then be used by importing the trait within individual modules:
An iterator that can collect into a slice.
