Struct rustc_data_structures::sync::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

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.
