# rayon-cond
[](https://crates.io/crates/rayon-cond)
[](https://docs.rs/rayon-cond)
[](https://cirrus-ci.com/github/cuviper/rayon-cond)
Experimental iterator wrapper that is conditionally parallel or serial, using
Rayon's `ParallelIterator` or the standard `Iterator` respectively.
## Usage
First add this crate to your `Cargo.toml`:
```toml
[dependencies]
rayon-cond = "0.4"
```
Then in your code, it may be used something like this:
```rust
use rayon_cond::CondIterator;
fn main() {
let args: Vec<_> = std::env::args().collect();
// Run in parallel if there are an even number of args
let par = args.len() % 2 == 0;
CondIterator::new(args, par).enumerate().for_each(|(i, arg)| {
println!("arg {}: {:?}", i, arg);
});
}
```
`rayon-cond` currently requires `rustc 1.63.0` or greater.
