Struct pond::Scope

pub struct Scope<'pool, 'scope> { /* private fields */ }

Represents the current scope, you can execute functions in it.

Implementations

impl<'pool, 'scope> Scope<'pool, 'scope>

pub fn with_state<StateMaker, State>(
    self,
    state_maker: StateMaker
) -> ScopeWithState<'pool, 'scope, State>where
    StateMaker: Fn() -> State + Send + 'scope,
    State: 'static,

Give each of the threads a state

The parameter is a closure that is run in each thread. The parameter finishes running before this function exits.

A new scope is returned that allows one to run jobs in the worker threads which can take the state parameter.

pub fn execute<F>(&self, f: F)where
    F: FnOnce() + Send + 'scope,

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.

This function may panic if a job that was previously executed 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.
