[−][src]Struct easy_parallel::Parallel
A builder that runs closures in parallel.
Implementations
impl<'a, T> Parallel<'a, T>
[src]
pub fn new() -> Parallel<'a, T>
[src]
Creates a builder for running closures in parallel.
Examples
use easy_parallel::Parallel; let p = Parallel::<()>::new();
pub fn add<F>(self, f: F) -> Parallel<'a, T> where
F: FnOnce() -> T + Send + 'a,
T: Send + 'a,
[src]
F: FnOnce() -> T + Send + 'a,
T: Send + 'a,
Adds a closure to the list.
Examples
use easy_parallel::Parallel; Parallel::new() .add(|| println!("hello from a thread")) .run();
pub fn each<A, I, F>(self, iter: I, f: F) -> Parallel<'a, T> where
I: IntoIterator<Item = A>,
F: FnOnce(A) -> T + Clone + Send + 'a,
A: Send + 'a,
T: Send + 'a,
[src]
I: IntoIterator<Item = A>,
F: FnOnce(A) -> T + Clone + Send + 'a,
A: Send + 'a,
T: Send + 'a,
Adds a cloned closure for each item in an iterator.
Each clone of the closure takes an item as an argument.
Examples
use easy_parallel::Parallel; Parallel::new() .each(0..5, |i| println!("hello from thread #{}", i)) .run();
pub fn run(self) -> Vec<T> where
T: Send + 'a,
[src]
T: Send + 'a,
Runs each closure on a separate thread and collects their results.
Results are collected in the order in which closures were added. One of the closures always runs on the main thread because there is no point in spawning an extra thread for it.
If a closure panics, panicking will resume in the main thread after all threads are joined.
Examples
use easy_parallel::Parallel; use std::thread; use std::time::Duration; let res = Parallel::new() .each(1..=3, |i| 10 * i) .add(|| 100) .run(); assert_eq!(res, [10, 20, 30, 100]);
