# Coil
An async task queue built with SQLx, Postgres, and Rayon
[](https://coveralls.io/github/insipx/coil?branch=master)
Coil is heavily inspired by and takes heavily from [swirl](https://github.com/sgrif/swirl). In many places of the codebase, code is very similiar.
Supports synchronous and asynchronous jobs. Synchronous jobs will be spawned into a threadpool managed by [`rayon`](https://github.com/rayon-rs/rayon). Async jobs will be spawned onto an executor. The only requirement is that the executor implements the futures `Spawn` trait. This way, `coil` supports `Tokio`, `smol`, and `async-std`.

### Examples
```rust
struct Size {
width: u32,
height: u32
}
#[coil::background_task]
async fn resize_image(id: u32, size: Size) -> Result<(), Error> {
// some work
}
```
With an environment
```rust
struct Size {
width: u32,
height: u32
}
struct Environment {
file_server_private_key: String,
http_client: http_lib::Client,
conn: sqlx::PgPool
}
#[coil::background_task]
async fn resize_image(env: &Environment, id: u32, size: Size) -> Result<(), Error> {
// some work
}
```
```rust
resize_image_with_env("tohru".to_string(), Size { height: 32, width: 32 }).enqueue(&pool).await;
let runner = coil::RunnerBuilder::new(env, Executor, pool)
.num_threads(8)
.build()
.unwrap();
runner.run_all_pending_tasks().await.unwrap()
```
### Differences from [`swirl`](https://github.com/sgrif/swirl)
- Supports asynchronous jobs/executors
- Supports jobs with generic arguments
- Serializes data into Postgres with Messagepack instead of JSON
- In asynchronous jobs, database queries will be run asynchronously with SQLx
- Migrations are included in the binary and exposed via a `migrate` fn.
- Enqueue is an `async fn`
