More iterator adaptors.
Add the following to your Cargo manifest.
toml
[dependencies]
itermore = "0.2"
And bring the [IterMore] trait into scope
rust
use itermore::IterMore;
The following additional iterator methods are provided.
next_arrayrust
let mut data = 1..5;
let [x, y] = data.next_array().unwrap();
assert_eq!(x, 1);
assert_eq!(y, 2);
The following adaptors are provided.
array_chunksSimilar to slice::array_chunks but for any iterator.
Returns an iterator over N elements of the iterator at a time.
rust
let data = [1, 1, 2, -2, 6, 0, 3, 1];
// ^-----^ ^------^
for [x, y, z] in data.iter().array_chunks() {
let sum = x + y + z;
assert_eq!(sum, 4);
}
array_windowsSimilar to slice::array_windows but for any iterator.
Returns an iterator over all contiguous windows of length N. The windows
overlap.
rust
let data = [10, 8, 6, 4];
// ^---^
// ^--^
// ^--^
for [x, y] in data.iter().array_windows() {
assert_eq!(x - y, 2);
}

at your option.
