Struct RuntimeHandle 

Source 
pub struct RuntimeHandle { /* private fields */ }
Expand description

An operator’s side of the runtime: where to send events, and where to get output samples from.

Implementations§

Source§

impl RuntimeHandle

Source

pub fn new(events_tx: Sender<OperatorEvent>, allocator: SharedAllocator) -> Self

Source

pub fn send_output( &self, output_id: DataId, parameters: MetadataParameters, array: &DoraArray, ) -> Result<()>

Encode array into a dora-owned sample on the calling (operator) thread and hand that to the runtime.

This is the only place an OperatorEvent::Output is built, so the ownership invariant that fixes dora-rs/dora#2742 holds for every operator backend: array is borrowed, never sent, and the caller drops it while it still holds whatever its language runtime needs to free it.

Source

pub fn report(&self, event: OperatorEvent)

Report a lifecycle event (finished, error, panic) to the runtime.
