Struct tokio::runtime::scheduler::current_thread::Context

pub(crate) struct Context {
    handle: Arc<Handle>,
    core: RefCell<Option<Box<Core>>>,
    pub(crate) defer: Defer,
}

Thread-local context.

pub(crate) to store in runtime::context.

Fields

handle: Arc<Handle>

Scheduler handle

core: RefCell<Option<Box<Core>>>

Scheduler core, enabling the holder of Context to execute the scheduler.

defer: Defer

Deferred tasks, usually ones that called task::yield_now().

Implementations

impl Context

fn run_task<R>(&self, core: Box<Core>, f: impl FnOnce() -> R) -> (Box<Core>, R)

Execute the closure with the given scheduler core stored in the thread-local context.

fn park(&self, core: Box<Core>, handle: &Handle) -> Box<Core>

Blocks the current thread until an event is received by the driver, including I/O events, timer events, …

fn park_yield(&self, core: Box<Core>, handle: &Handle) -> Box<Core>

Checks the driver for new events without blocking the thread.

fn enter<R>(&self, core: Box<Core>, f: impl FnOnce() -> R) -> (Box<Core>, R)

pub(crate) fn defer(&self, waker: &Waker)
