Parallel runner defining how the threads must be spawned and job must be distributed.

Required Associated Types

type Executor: ParallelExecutor

Parallel executor responsible for distribution of tasks to the threads.

type ThreadPool: ParThreadPool

Thread pool responsible for providing threads to the parallel computation.

Required Methods

fn thread_pool(&self) -> &Self::ThreadPool

Reference to the underlying thread pool.

fn thread_pool_mut(&mut self) -> &mut Self::ThreadPool

Mutable reference to the underlying thread pool.

Provided Methods

fn new_executor( &self, kind: ComputationKind, params: Params, initial_input_len: Option<usize>, ) -> Self::Executor

Creates a new parallel executor for a parallel computation.

fn run_all<I, F>( &mut self, params: Params, iter: I, kind: ComputationKind, thread_do: F, ) -> NumSpawned

where I: ConcurrentIter, F: Fn(NumSpawned, &I, &<<Self as ParallelRunner>::Executor as ParallelExecutor>::SharedState, <<Self as ParallelRunner>::Executor as ParallelExecutor>::ThreadExecutor) + Sync,

Runs thread_do using threads provided by the thread pool.

fn map_all<F, I, M, T>( &mut self, params: Params, iter: I, kind: ComputationKind, thread_map: M, ) -> (NumSpawned, Result<Vec<T>, F::Error>)

where F: Fallibility, I: ConcurrentIter, M: Fn(NumSpawned, &I, &<<Self as ParallelRunner>::Executor as ParallelExecutor>::SharedState, <<Self as ParallelRunner>::Executor as ParallelExecutor>::ThreadExecutor) -> Result<T, F::Error> + Sync, T: Send, F::Error: Send,

Runs thread_map using threads provided by the thread pool.

fn map_infallible<I, M, T>( &mut self, params: Params, iter: I, kind: ComputationKind, thread_map: M, ) -> (NumSpawned, Result<Vec<T>, Never>)

where I: ConcurrentIter, M: Fn(NumSpawned, &I, &<<Self as ParallelRunner>::Executor as ParallelExecutor>::SharedState, <<Self as ParallelRunner>::Executor as ParallelExecutor>::ThreadExecutor) -> Result<T, Never> + Sync, T: Send,

Runs infallible thread_map using threads provided by the thread pool.

fn max_num_threads_for_computation( &self, params: Params, iter_len: Option<usize>, ) -> NonZeroUsize

Returns the maximum number of threads that can be used for the computation defined by the params and input iter_len.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
