Asynchronous programming foundations: futures, streams, combinators (join!, select!) and utilities enabling ergonomic async control flow; faithful line-by-line transliteration preserving upstream semantics and source provenance.
This is a Kotlin Multiplatform line-by-line transliteration port of rust-lang/futures-rs.
Original Project: This port is based on rust-lang/futures-rs. 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.
The text below is reproduced and lightly edited from
https://github.com/rust-lang/futures-rs. It is the upstream project's own description and remains under the upstream authors' authorship; links have been rewritten to absolute upstream URLs so they continue to resolve from this repository.
Zero-cost asynchronous programming in Rust
futures-rs is a library providing the foundations for asynchronous programming in Rust.
It includes key trait definitions like Stream, as well as utilities like join!,
select!, and various futures combinator methods which enable expressive asynchronous
control flow.
Add this to your Cargo.toml:
[dependencies]
futures = "0.3"The current futures requires Rust 1.71 or later.
Futures-rs works without the standard library, such as in bare metal environments.
However, it has a significantly reduced API surface. To use futures-rs in
a #[no_std] environment, use:
[dependencies]
futures = { version = "0.3", default-features = false }Licensed under either of Apache License, Version 2.0 or MIT license at your option.
Unless you explicitly state otherwise, any contribution intentionally submitted for inclusion in the work by you, as defined in the Apache-2.0 license, shall be dual licensed as above, without any additional terms or conditions.
