§inner: Arc<Inner>

Implementations§

source§

impl Context

source

pub fn with<F, R>(f: F) -> R
where F: FnOnce(&Context) -> R,

Creates a new context for the duration of the closure.

source

fn new() -> Context

Creates a new Context.

source

fn reset(&self)

Resets select and packet.

source

pub fn try_select(&self, select: Selected) -> Result<(), Selected>

Attempts to select an operation.

On failure, the previously selected operation is returned.

source

pub fn selected(&self) -> Selected

Returns the selected operation.

source

pub fn store_packet(&self, packet: *mut ())

Stores a packet.

This method must be called after try_select succeeds and there is a packet to provide.

source

pub fn wait_packet(&self) -> *mut ()

Waits until a packet is provided and returns it.

source

pub fn wait_until(&self, deadline: Option<Instant>) -> Selected

Waits until an operation is selected and returns it.

If the deadline is reached, Selected::Aborted will be selected.

source

pub fn unpark(&self)

Unparks the thread this context belongs to.

source

pub fn thread_id(&self) -> ThreadId

Returns the id of the thread this context belongs to.
