Struct tokio_executor::park::ParkThread

[+] Show declaration

pub struct ParkThread { /* fields omitted */ }

[−] Expand description

Blocks the current thread using a condition variable.

Implements the Park functionality by using a condition variable. An atomic variable is also used to avoid using the condition variable if possible.

The condition variable is cached in a thread-local variable and is shared across all ParkThread instances created on the same thread. This also means that an instance of ParkThread might be unblocked by a handle associated with a different ParkThread instance.

Methods

impl ParkThread

[−]

pub fn new() -> ParkThread

[−]

Create a new ParkThread handle for the current thread.

This type cannot be moved to other threads, so it should be created on the thread that the caller intends to park.
