pub struct WorkerLocal<T> {
    locals: Box<[CacheAligned<T>]>,
    registry: Registry,
}
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§

§locals: Box<[CacheAligned<T>]>§registry: Registry
