Use chunks(n) for fixed-size groups and windows(n) for overlapping sliding views on Rust slices.
Use chunks(n) to split a slice into fixed-size sub-slices and windows(n) to create an iterator of overlapping sub-slices of size n.
let data = [1, 2, 3, 4, 5];
// Fixed-size chunks: [1, 2], [3, 4], [5]
for chunk in data.chunks(2) {
println!("{:?}", chunk);
}
// Overlapping windows: [1, 2, 3], [2, 3, 4], [3, 4, 5]
for window in data.windows(3) {
println!("{:?}", window);
}
These methods let you process data in groups without copying it. chunks breaks your list into separate, non-overlapping buckets of a specific size, like sorting mail into bins. windows slides a view across your list to look at every possible group of neighbors, like checking every three consecutive numbers in a sequence.
