## Getting help
|
|
|
|
Serde is one of the most widely used Rust libraries so any place that Rustaceans
|
|
congregate will be able to help you out. For chat, consider trying the
|
|
[#rust-questions] or [#rust-beginners] channels of the unofficial community
|
|
Discord (invite: <https://discord.gg/rust-lang-community>), the [#rust-usage] or
|
|
[#beginners] channels of the official Rust Project Discord (invite:
|
|
<https://discord.gg/rust-lang>), or the [#general][zulip] stream in Zulip. For
|
|
asynchronous, consider the [\[rust\] tag on StackOverflow][stackoverflow], the
|
|
[/r/rust] subreddit which has a pinned weekly easy questions post, or the Rust
|
|
[Discourse forum][discourse]. It's acceptable to file a support issue in this
|
|
repo but they tend not to get as many eyes as any of the above and may get
|
|
closed without a response after some time.
