Struct `Context`

pub struct Context { pub(in ::sync::mpmc::context) inner: Arc<Inner> }

Thread-local context.

Fields

inner: Arc<Inner>

Implementations

`impl Context`

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

Creates a new context for the duration of the closure.

fn new() -> Context

Creates a new Context.

fn reset(&self)

Resets select and packet.

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

Attempts to select an operation.

On failure, the previously selected operation is returned.

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.

unsafe 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.

Safety

This may only be called from the thread this Context belongs to.

fn unpark(&self)

Unparks the thread this context belongs to.

fn thread_id(&self) -> usize

Returns the id of the thread this context belongs to.
