For chat, consider trying the 80[#general] or [#beginners] channels of the unofficial community Discord, the 81[#rust-usage] channel of the official Rust Project Discord, or the 82[#general][zulip] stream in Zulip. For asynchronous, consider the [\[rust\] tag 83on StackOverflow][stackoverflow], the [/r/rust] subreddit which has a pinned 84weekly easy questions post, or the Rust [Discourse forum][discourse]. It's 85acceptable to file a support issue in this repo but they tend not to get as many 86eyes as any of the above and may get closed without a response after some time. 87 88[#general]: https://discord.com/channels/273534239310479360/274215136414400513 89[#beginners]: https://discord.com/channels/273534239310479360/273541522815713281 90[#rust-usage]: https://discord.com/channels/442252698964721669/443150878111694848 91[zulip]: https://rust-lang.zulipchat.com/#narrow/stream/122651-general 92[stackoverflow]: https://stackoverflow.com/questions/tagged/rust 93[/r/rust]: https://www.reddit.com/r/rust 94[discourse]: https://users.rust-lang.org 95 96<br> 97 98#### License 99 100<sup> 101Licensed under either of <a href="LICENSE-APACHE">Apache License, Version 1022.0</a> or <a href="LICENSE-MIT">MIT license</a> at your option. 103</sup> 104 105<br> 106 107<sub> 108Unless you explicitly state otherwise, any contribution intentionally submitted 109for inclusion in Serde by you, as defined in the Apache-2.0 license, shall be 110dual licensed as above, without any additional terms or conditions. 111</sub> 112
