Struct rustc_rayon_core::WorkerLocal

pub struct WorkerLocal<T> { /* fields omitted */ }

Holds worker-locals values for each thread in a thread pool. You can only access the worker local value through the Deref impl on the thread pool it was constructed on. It will panic otherwise

Implementations

impl<T> WorkerLocal<T>

pub fn new<F: FnMut(usize) -> T>(initial: F) -> WorkerLocal<T>

Creates a new worker local where the initial closure computes the value this worker local should take for each thread in the thread pool.

pub fn into_inner(self) -> Vec<T>

Returns the worker-local value for each thread

impl<T> WorkerLocal<Vec<T>>

pub fn join(self) -> Vec<T>

Joins the elements of all the worker locals into one Vec

Trait Implementations

impl<T: Debug> Debug for WorkerLocal<T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<T> Deref for WorkerLocal<T>

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &T

Dereferences the value.

impl<T: Send> Sync for WorkerLocal<T>

We prevent concurrent access to the underlying value in the Deref impl, thus any values safe to send across threads can be used with WorkerLocal.
