source · pub struct ScopeWithState<'pool, 'scope, State>where
State: 'static,{ /* private fields */ }
Expand description
Like Scope
, but the execute
function
accepts worker closures with a State parameter.

Execute a job on one of the threads in the threadpool.
The closure is called from one of the threads. If the threadpool has a specified backlog, then this function blocks until the threadpool finishes a job.
The closure is passed a mutable reference to the
the state produced by the function passed to Scope::with_state
This function may panic if a job that was previously
execute
d has panicked. This way, your program terminates
as soon as a panic occurs. If you don’t call this function
again after a panic occurs, then Pool::scoped
will panic before it completes.
