Struct EscapeHatch 

pub struct EscapeHatch { /* private fields */ }

Used for forwarding “escape hatch” calls (a run_function sent from a child runtime back to an ancestor).

Implementations

impl EscapeHatch

pub fn this_runtime(target: Callback) -> Self

An instance whereby run_functions execute on this runtime, given a Callback telling child workers how to connect to this runtime.

pub fn new(parent: Option<FunctionForwarder>, this_runtime: Callback) -> Self

Creates a new instance from a Callback to this runtime and optionally a parent. If parent is non-null, then this_runtime should identify parent in the servers EscapeHatch-forwarding map.

pub fn spawn_escape(&self, function: FunctionName) -> Option<RuntimeOperation>

Cross-fingers that this runs a function. Deliberately no way to specify a location.

Trait Implementations

impl Clone for EscapeHatch

fn clone(&self) -> EscapeHatch

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
