Crate rayon

Modules

collections	This module contains the parallel iterator types for standard collections. You will rarely need to interact with it directly unless you have need to name one of the iterator types.
iter	The ParallelIterator module makes it easy to write parallel programs using an iterator-style interface. To get access to all the methods you want, the easiest is to write use rayon::prelude::*; at the top of your module, which will import the various traits and methods you need.
option	This module contains the parallel iterator types for options (Option<T>). You will rarely need to interact with it directly unless you have need to name one of the iterator types.
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	This module contains the parallel iterator types for ranges (Range<T>); this is the type for values created by a a..b expression. You will rarely need to interact with it directly unless you have need to name one of the iterator types.
result	This module contains the parallel iterator types for results (Result<T, E>). You will rarely need to interact with it directly unless you have need to name one of the iterator types.
slice	This module contains the parallel iterator types for slices ([T]). You will rarely need to interact with it directly unless you have need to name one of those types.
str	This module contains extension methods for String that expose parallel iterators, such as par_split_whitespace(). You will rarely need to interact with it directly, since if you add use rayon::prelude::* to your file, that will include the helper traits defined in this module.
vec	This module contains the parallel iterator types for vectors (Vec<T>). You will rarely need to interact with it directly unless you have need to name one of those types.

Structs

Configuration	[ Deprecated ] Contains the rayon thread pool configuration. Use ThreadPoolBuilder instead.
Scope	Represents a fork-join scope which can be used to spawn any number of tasks. See scope() for more information.
ThreadPool	Represents a user created thread-pool.

Functions

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.
initialize	[ Deprecated ] Deprecated in favor of ThreadPoolBuilder::build_global.
join	Takes two closures and potentially runs them in parallel. It returns a pair of the results from those closures.
scope	Create 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.
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.
split	The split function takes arbitrary data and a closure that knows how to split it, and turns this into a ParallelIterator.
