# Conqueue

[](https://crates.io/crates/conqueue)
Conqueue is yet another multi-producer, single-consumer queue (MPSC) for the Rust programming language.
## Getting Started
To get started, add the following to your `Cargo.toml` file:
```toml
[dependencies]
conqueue = "0.2.1"
```
Then, at the root of your crate:
```rust
extern crate conqueue
```
Finally, create a sender/receiver pair. The sender may be cloned to
allow concurrent producers, and it is both `Send` and `Sync`. The
receiver is `Send` so it may be moved to other threads.
```rust
let (tx1, mut rx) = conqueue::Queue::unbounded();
let tx2 = tx1.clone();
tx1.push(1);
tx2.push(2);
while let Some(value) = rx.pop() {
println!("popped: {}", value);
}
```
## Release Notes
### 0.2.1 - 2019-08-29
* Republish to fix README.md on Crates.io
### 0.2.0 - 2019-08-29
* Items that are pushed into a queue are now dropped if there is no receiver
### 0.1.1 - 2019-07-30
* Senders should be `Send`
### 0.1.0 - 2019-07-30
* Initial release. Likely not production ready.
## Developer Notes
To run the tests, execute the following:
```bash
cargo test
```
To run a benchmark for the queue, execute the following:
```bash
cargo test --release -- --ignored --nocapture
```
To release the create, perform the following:
1. Edit `Cargo.toml`, bumping the version as appropriate.
2. Edit `README.md`, adding an entry to the Release Notes, and updating the TOML snippet's version.
3. Commit these changes and push them to `master`.
4. Create and push a tag that starts with "v" -- e.g. "v0.2.0"

This code is largely based on [majek](https://github.com/majek)'s
implementation of Michael-Scott queue. You can find the
