rustc_data_structures::sync::worker_local

Struct WorkerLocal

source 
pub struct WorkerLocal<T> {
    local: T,
}
Expand description

Holds worker local values for each possible thread in a registry. You can only access the worker local value through the Deref impl on the registry associated with the thread it was created on. It will panic otherwise.

Fields§

§local: T

Implementations§

source§

impl<T> WorkerLocal<T>

source

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 registry.

source

pub fn into_inner(self) -> impl Iterator<Item = T>

Returns the worker-local values for each thread

Layout§

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
