posix_mq
========
[](https://crates.io/crates/posix_mq)
This is a simple, relatively high-level library for the POSIX [message queue API][]. It wraps the lower-level API in a
simpler interface with more robust error handling.
Check out this project's [sister library][] in Kotlin.
Usage example:
```rust
// Values that need to undergo validation are wrapped in safe types:
let name = Name::new("/test-queue").unwrap();
// Queue creation with system defaults is simple:
let queue = Queue::open_or_create(name).expect("Opening queue failed");
// Sending a message:
let message = Message {
data: "test-message".as_bytes().to_vec(),
priority: 0,
};
queue.send(&message).expect("message sending failed");
// ... and receiving it!
let result = queue.receive().expect("message receiving failed");
```
## Development
Development happens in the [TVL
monorepo](https://cs.tvl.fyi/depot/-/tree/ops/posix_mq.rs).
Starting from version `3771.0.0`, the version numbers correspond to
_revisions_ of the TVL repository, available as git refs (e.g.
`refs/r/3771`).
See the TVL documentation for more information about how to contribute
to the codebase.
