# plmap
Parallel pipelined map over iterators for rust.
## Documentation
[docs.rs/plmap](https://docs.rs/plmap/)
## Example
Parallel pipelined mapping:
```
// Import the iterator extension trait.
use plmap::PipelineMap;
// Map over an iterator in parallel with 5 worker threads.
fn example() {
for i in (0..100).plmap(5, |x| x * 2) {
println!("i={}", i);
}
}
```
Map with your own type instead of a function:
```
use plmap::{Mapper, PipelineMap};
// The type must support clone as each worker thread gets a copy.
#[derive(Clone)]
struct CustomMapper {}
impl Mapper<i32> for CustomMapper {
type Out = i64;
fn apply(&mut self, x: i32) -> i64 {
(x * 2) as i64
}
}
fn custom_mapper() {
for i in (0..100).plmap(5, CustomMapper{}) {
println!("i={}", i);
}
}
```
