Methods

impl Context

[−]

pub fn new(     local_sync_node: LocalSyncNodeRef,     pool_handle: CpuPool,     remote: Remote,     config: Config ) -> Result<Self, Box<Error>>

[−]

Creates new context with reference to local sync node, thread pool and event loop.

pub fn spawn<F>(&self, f: F) where     F: Future + Send + 'static,     F::Item: Send + 'static,     F::Error: Send + 'static,

[−]

Spawns a future using thread pool and schedules execution of it with event loop handle.

pub fn execute_after<F>(&self, duration: Duration, f: F) where     F: FnOnce() + 'static + Send,

[−]

Schedules execution of function in future. Use wisely, it keeps used objects in memory until after it is resolved.
