Modules

array
Parallel iterator types for arrays ([T; N])
collections
Parallel iterator types for standard collections
iter
Traits for writing parallel programs using an iterator-style interface
option
Parallel iterator types for options
prelude
The rayon prelude imports the various ParallelIterator traits. The intention is that one can include use rayon::prelude::* and have easy access to the various traits and methods you will need.
range
Parallel iterator types for ranges, the type for values created by a..b expressions
range_inclusive
Parallel iterator types for inclusive ranges, the type for values created by a..=b expressions
result
Parallel iterator types for results
slice
Parallel iterator types for slices
str
Parallel iterator types for strings
string
This module contains the parallel iterator types for owned strings (String). You will rarely need to interact with it directly unless you have need to name one of the iterator types.
vec
Parallel iterator types for vectors (Vec<T>)

Structs

BroadcastContext
Provides context to a closure called by broadcast.
FnContext
Provides the calling context to a closure called by join_context.
Scope
Represents a fork-join scope which can be used to spawn any number of tasks. See scope() for more information.
ScopeFifo
Represents a fork-join scope which can be used to spawn any number of tasks. Those spawned from the same thread are prioritized in relative FIFO order. See scope_fifo() for more information.
ThreadBuilder
Thread builder used for customization via ThreadPoolBuilder::spawn_handler.
ThreadPool
Represents a user created thread-pool.
ThreadPoolBuildError
Error when initializing a thread pool.
ThreadPoolBuilder
Used to create a new ThreadPool or to configure the global rayon thread pool.

Functions

broadcast
Executes op within every thread in the current threadpool. If this is called from a non-Rayon thread, it will execute in the global threadpool. Any attempts to use join, scope, or parallel iterators will then operate within that threadpool. When the call has completed on each thread, returns a vector containing all of their return values.
current_num_threads
Returns the number of threads in the current registry. If this code is executing within a Rayon thread-pool, then this will be the number of threads for the thread-pool of the current thread. Otherwise, it will be the number of threads for the global thread-pool.
current_thread_index
If called from a Rayon worker thread, returns the index of that thread within its current pool; if not called from a Rayon thread, returns None.
in_place_scope
Creates a “fork-join” scope s and invokes the closure with a reference to s. This closure can then spawn asynchronous tasks into s. Those tasks may run asynchronously with respect to the closure; they may themselves spawn additional tasks into s. When the closure returns, it will block until all tasks that have been spawned into s complete.
in_place_scope_fifo
Creates a “fork-join” scope s with FIFO order, and invokes the closure with a reference to s. This closure can then spawn asynchronous tasks into s. Those tasks may run asynchronously with respect to the closure; they may themselves spawn additional tasks into s. When the closure returns, it will block until all tasks that have been spawned into s complete.
join
Takes two closures and potentially runs them in parallel. It returns a pair of the results from those closures.
join_context
Identical to join, except that the closures have a parameter that provides context for the way the closure has been called, especially indicating whether they’re executing on a different thread than where join_context was called. This will occur if the second job is stolen by a different thread, or if join_context was called from outside the thread pool to begin with.
max_num_threads
Returns the maximum number of threads that Rayon supports in a single thread-pool.
scope
Creates a “fork-join” scope s and invokes the closure with a reference to s. This closure can then spawn asynchronous tasks into s. Those tasks may run asynchronously with respect to the closure; they may themselves spawn additional tasks into s. When the closure returns, it will block until all tasks that have been spawned into s complete.
scope_fifo
Creates a “fork-join” scope s with FIFO order, and invokes the closure with a reference to s. This closure can then spawn asynchronous tasks into s. Those tasks may run asynchronously with respect to the closure; they may themselves spawn additional tasks into s. When the closure returns, it will block until all tasks that have been spawned into s complete.
spawn
Fires off a task into the Rayon threadpool in the “static” or “global” scope. Just like a standard thread, this task is not tied to the current stack frame, and hence it cannot hold any references other than those with 'static lifetime. If you want to spawn a task that references stack data, use the scope() function to create a scope.
spawn_broadcast
Spawns an asynchronous task on every thread in this thread-pool. This task will run in the implicit, global scope, which means that it may outlast the current stack frame – therefore, it cannot capture any references onto the stack (you will likely need a move closure).
spawn_fifo
Fires off a task into the Rayon threadpool in the “static” or “global” scope. Just like a standard thread, this task is not tied to the current stack frame, and hence it cannot hold any references other than those with 'static lifetime. If you want to spawn a task that references stack data, use the scope_fifo() function to create a scope.
