# Socket2Socket2 is a crate that provides utilities for creating and using sockets.The goal of this crate is to create and use a socket using advancedconfiguration options (those that are not available in the types in the standardlibrary) without using any unsafe code.This crate provides as direct as possible access to the system's functionalityfor sockets, this means little effort to provide cross-platform utilities. It isup to the user to know how to use sockets when using this crate. *If you don'tknow how to create a socket using libc/system calls then this crate is not foryou*. Most, if not all, functions directly relate to the equivalent system callwith no error handling applied, so no handling errors such as `EINTR`. As aresult using this crate can be a little wordy, but it should give you maximalflexibility over configuration of sockets.See the [API documentation] for more.[API documentation]: https://docs.rs/socket2# BranchesCurrently Socket2 supports the following versions: * v0.6 developed in the master branch * v0.5 developed in the [v0.5.x branch] * v0.4 developed in the [v0.4.x branch][v0.5.x branch]: https://github.com/rust-lang/socket2/tree/v0.5.x[v0.4.x branch]: https://github.com/rust-lang/socket2/tree/v0.4.x# OS supportSocket2 attempts to support the same OS/architectures as Rust does, seehttps://doc.rust-lang.org/nightly/rustc/platform-support.html. However this isnot always possible, below is current list of support OSs.*If your favorite OS is not on the list consider contributing it!*### Tier 1These OSs are tested with each commit in the CI and must always pass the tests.All functions/types/etc., excluding ones behind the `all` feature, must work onthese OSs.* Linux* macOS* Windows### Tier 2These OSs are currently build in the CI, but not tested. Not allfunctions/types/etc. may work on these OSs, even ones **not** behind the `all`feature flag.* Android* FreeBSD* Fuchsia* iOS* illumos* NetBSD* Redox* Solaris* OpenHarmony# Minimum Supported Rust Version (MSRV)Socket2 uses 1.70.0 as MSRV.# LicenseThis project is licensed under either of * Apache License, Version 2.0, ([LICENSE-APACHE](LICENSE-APACHE) or   https://www.apache.org/licenses/LICENSE-2.0) * MIT license ([LICENSE-MIT](LICENSE-MIT) or   https://opensource.org/licenses/MIT)at your option.### ContributionUnless you explicitly state otherwise, any contribution intentionally submittedfor inclusion in this project by you, as defined in the Apache-2.0 license,shall be dual licensed as above, without any additional terms or conditions.
