Rust license

Crates that simply need the maximum compatibility with the Rust ecosystem are recommended to do the same, in the manner described herein. Other options are described below. These guidelines are concerned with matters of interoperability with Rust, and are not comprehensive over licensing options. To apply the Rust license rust license your project, define the license field in your Cargo, rust license.

The rustc compiler source and standard library are dual licensed under the Apache License v2. In general, reviewers need to be looking not only for the code quality of contributions but also that they are properly licensed. We have some tips below for things to look out for when reviewing, but if you ever feel uncertain as to whether some code might be properly licensed, err on the safe side — reach out to the Council or Compiler Team Leads for feedback! Contributions to rustc, especially around platform and compiler intrinsics, often include porting over work from other projects, mainly LLVM and GCC. In general, taking inspiration from other codebases is fine, but please exercise caution when porting code.

This is the most permissive Creative Commons license, and allows reuse and modifications for any purpose. Note that use of these logos, and the Rust and Cargo names, is also governed by trademark; our trademark policy is described below. But at the same time, we want to allow for as much creative use of these brands as we can. The policy laid out here explains how we strike a balance. If you want to use these names or brands, especially in a commercial way, please read this page or feel free to reach out and ask us about it! In either case, the most important rule is that uses of the trademarks cannot appear official or imply any endorsement by the Rust project. The Rust programming language is an open source, community project governed by a core team. This document provides information about use of the Rust Trademarks specific to a programming language, as well as examples of common ways people might want to use these trademarks, with explanations as to whether those uses are OK or not or require permission. This document supplements the official Mozilla trademark policy which governs use of all Mozilla trademarks. Trademarks are names and designs that tell the world the source of a good or service. Protecting trademarks for an open source project is particularly important. The most basic rule is that the Rust trademarks cannot be used in ways that appear to a casual observer official, affiliated, or endorsed by the Rust project or Mozilla, unless you have written permission from the Rust core team.

A library for generating and verifying license keys without requiring an Internet connection. For further protection, you can of course validate the license key over the Internet. Every license key consists of a seed, a payload and a checksum. Each byte in the payload is an operation of the seed and an initialization vector. The bit checksum is there to quickly check if the key is valid at all, while the seed is a bit hash of something that identifies the license key owner such as an e-mail address or similar. The size of the payload depends on how big the initialization vector is. In the example below, we are using a 5-byte intitialization vector which results in a 5-byte payload. Represent a hasher that turns the seed and a part of the initialization vector into a license key byte. Owners patriksvensson.

As with any trademark, the Rust and Cargo word marks can be used with minimal restriction to refer to the Rust programming language and the Cargo package manager and registry. Distributing a modified version of the Rust programming language or the Cargo package manager and calling it Rust or Cargo requires explicit, written permission from the Rust core team.

We will usually allow these uses as long as 1 it is clearly communicated that the merchandise is not in any way an official part of the Rust project and 2 it is clearly communicated whether profits benefit the Rust project. They may not be used: to refer to any other programming language; in a way that is misleading or may imply association of unrelated modules, tools, documentation, or other resources with the Rust programming language; in ways that confuse the community as to whether the Rust programming language is open source and free to use.

To apply the Rust license to your project, define the license field in your Cargo. The Rust programming language is an open source, community project governed by a core team. Contribution Unless you explicitly state otherwise, any contribution intentionally submitted for inclusion in the work by you, as defined in the Apache We will usually allow these uses as long as the modifications are 1 relatively small and 2 very clearly communicated to end-users. That would require Rust itself to be licensed under the GPL. Using the Rust trademarks on t-shirts, hats, and other artwork or merchandise, even in modified form, is allowed for your personal use or for use by a small group of community members, as long as they are not sold.
