Extra iterator adaptors, combinators and utilities for fluent sequence processing — combinations, permutations, grouping, chunking, sliding windows, zipping, unique, cartesian products.
This is a Kotlin Multiplatform line-by-line transliteration port of rust-itertools/itertools.
Original Project: This port is based on rust-itertools/itertools. All design credit and project intent belong to the upstream authors; this repository is a faithful port to Kotlin Multiplatform with no behavioural changes intended.
This is an in-progress port. The goal is feature parity with the upstream Rust crate while providing a native Kotlin Multiplatform API. Every Kotlin file carries a // port-lint: source <path> header naming its upstream Rust counterpart so the AST-distance tool can track provenance.
