It's acceptable to file a support issue in this 87repo but they tend not to get as many eyes as any of the above and may get 88closed without a response after some time. 89 90[#rust-questions]: https://discord.com/channels/273534239310479360/274215136414400513 91[#rust-beginners]: https://discord.com/channels/273534239310479360/273541522815713281 92[#rust-usage]: https://discord.com/channels/442252698964721669/443150878111694848 93[#beginners]: https://discord.com/channels/442252698964721669/448238009733742612 94[zulip]: https://rust-lang.zulipchat.com/#narrow/stream/122651-general 95[stackoverflow]: https://stackoverflow.com/questions/tagged/rust 96[/r/rust]: https://www.reddit.com/r/rust 97[discourse]: https://users.rust-lang.org 98 99<br> 100 101#### License 102 103<sup> 104Licensed under either of <a href="LICENSE-APACHE">Apache License, Version 1052.0</a> or <a href="LICENSE-MIT">MIT license</a> at your option. 106</sup> 107 108<br> 109 110<sub> 111Unless you explicitly state otherwise, any contribution intentionally submitted 112for inclusion in Serde by you, as defined in the Apache-2.0 license, shall be 113dual licensed as above, without any additional terms or conditions. 114</sub> 115
