Struct TaskSpawner 

pub struct TaskSpawner { /* private fields */ }

A generation-bound capability for cancellation-aware child tasks.

Implementations

impl TaskSpawner

pub fn cancellation_token(&self) -> CancellationToken

Returns a non-authoritative cancellation signal for this generation.

pub fn spawn<F>(&self, future: F) -> Result<(), TaskSpawnError>

where F: Future<Output = ()> + Send + 'static,

Registers future before allowing it to poll.

Errors

Returns an error when this spawner no longer belongs to the open generation.

pub fn spawn_named<F>( &self, name: &'static str, future: F, ) -> Result<TaskRef, TaskSpawnError>

where F: Future<Output = ()> + Send + 'static,

Registers a named future before allowing it to poll.

The returned reference observes identity and terminal state without owning cancellation or joining. The task may reach a terminal state before this method returns.

Errors

Returns an error when this spawner no longer belongs to the open generation.

Panics

Panics if the process exhausts the u64 task identifier space.
