# procspawn
[](https://crates.io/crates/procspawn)
[](https://docs.rs/procspawn)
This crate provides the ability to spawn processes with a function similar
to `thread::spawn`. Instead of closures it passes [`serde`](https://serde.rs/)
serializable objects. The return value from the spawned closure also must be
serializable and can then be retrieved from the returned join handle.
If the spawned function causes a panic it will also be serialized across
the process boundaries.
## Example
Step 1: invoke `procspawn::init` as the first operation in `main`. A spawned
process starts the executable again and re-enters `main`, so any code before
this call runs again in every child process. Keep application setup and other
side effects after it.
```rust
fn main() {
procspawn::init();
// Application setup starts here.
}
```
Step 2: now you can start spawning functions:
```rust
let data = vec![1, 2, 3, 4];
data.into_iter().sum::<i64>()
});
let result = handle.join().unwrap();
```
