Crate slicetools [−] [src]

This crate aims to provide various tools for slices.

This crate use its own streaming iterator due to the lack of generic associated type in the language: you therefore cannot use those iterators with the for control flow. Use the while let control flow, or the macro helper, as you can see below.

Example

use slicetools::*;

let mut v = vec![1, 2, 3, 4];
{
    let mut it = v.pairs_mut();
     
    while let Some((a, b)) = it.next() {
        if *b > *a {
            *a += 1;
        }
    }
}
assert_eq!(v, &[4, 4, 4, 4]);

Or, with the helper macro (do not forget to #[macro_use]):

use slicetools::*;
 
let mut v = vec![1, 2, 3, 4];
 
stream!( v.pairs_mut() => (a, b) in {
    if *b > *a {
        *a += 1;
    }
});
assert_eq!(v, &[4, 4, 4, 4]);

Macros

stream

Convenient helper to use easily the custom streaming iterator.

Traits

SliceTools	A trait to extend slices and `Vec`s with streaming iterators.
StreamerMut	A trait to implement streaming iterators that can return mutable reference to oneself.
