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
Cargo.toml:
[dependencies]
slicetools = "0.2.*"
main.rs:
extern crate slicetools;
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:
#[macro_use] extern crate slicetools;
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]);
Changelog
0.3.*
- Add 3 new extensions to take groups of items.
0.2.*
-
Use own streaming iterator instead of regular iterator that was unsafe (allowed multiple mutable borrowing on the same item).
-
Add a new streamer for doing a cartesian product between two slices.
