It is built upon [Serde], a high performance generic serialization framework and [rust-url], a URL parser for Rust. [rust-url]: https://github.com/servo/rust-url [Serde]: https://github.com/serde-rs/serde [urlencoded]: https://url.spec.whatwg.org/#application/x-www-form-urlencoded Installation ============ This crate works with Cargo and can be found on [crates.io] with a `Cargo.toml` like: ```toml [dependencies] serde_urlencoded = "0.7" ``` The documentation is available on [docs.rs]. [crates.io]: https://crates.io/crates/serde_urlencoded [docs.rs]: https://docs.rs/serde_urlencoded/0.7.1/serde_urlencoded/ ## Getting help Serde developers live in the #serde channel on [`irc.mozilla.org`](https://wiki.mozilla.org/IRC) and most rust-url developers live in the #servo one. The #rust channel is also a good resource with generally faster response time but less specific knowledge about Serde, rust-url or this crate. If IRC is not your thing, we are happy to respond to [GitHub issues](https://github.com/nox/serde_urlencoded/issues/new) as well. ## License serde_urlencoded is licensed under either of * Apache License, Version 2.0, ([LICENSE-APACHE](LICENSE-APACHE) or http://www.apache.org/licenses/LICENSE-2.0) * MIT license ([LICENSE-MIT](LICENSE-MIT) or http://opensource.org/licenses/MIT) at your option. ### Contribution Unless you explicitly state otherwise, any contribution intentionally submitted for inclusion in serde_urlencoded by you, as defined in the Apache-2.0 license, shall be dual licensed as above, without any additional terms or conditions. serde_urlencoded-0.7.1/rustfmt.toml000064400000000000000000000001710072674642500155670ustar 00000000000000match_block_trailing_comma = false max_width = 80 newline_style = "Unix" reorder_imports = true use_try_shorthand = true serde_urlencoded-0.7.1/src/de.rs000064400000000000000000000172170072674642500147240ustar 00000000000000//!
