Collect an iterator into a slice.
Rust comes with the Iterator::collect method for collecting an iterator's items into
a heap-allocated 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
otherwise.)
The trait is automatically implemented for any type that implements Iterator.
```rust use collect_slice::CollectSlice;
let mut orig = [0; 8]; (0..8).map(|i| i * 2).collectslicechecked(&mut orig[..]); assert_eq!(orig, [0, 2, 4, 6, 8, 10, 12, 14]);
let mut buf = [42; 8]; orig.iter() .map(|&x| x + 10) .collectslicechecked(&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 Cargo.toml:
toml
[dependencies]
collect_slice = "^1.2.0"
and importing it in the crate root:
rust
extern crate collect_slice;
The provided methods can then be used by importing the trait within individual
modules:
rust
use collect_slice::CollectSlice;
