Expand description

Process-local cooperative cancellation signal for a live execution attempt.

Required Methods§

Source

fn request_cancel<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, key: &'life1 ThreadKey, context: &'life2 InvocationContext, ) -> Pin<Box<dyn Future<Output = Result<(), StoreError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Requests cancellation idempotently.

The full invocation context prevents collisions between users, scopes, threads, and runs inside one process.

Source

fn is_cancel_requested<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, key: &'life1 ThreadKey, run_id: &'life2 RunId, ) -> Pin<Box<dyn Future<Output = Result<bool, StoreError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Returns whether cancellation has been requested.

Source

fn wait_for_cancel<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, key: &'life1 ThreadKey, run_id: &'life2 RunId, ) -> Pin<Box<dyn Future<Output = Result<(), StoreError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Waits until cancellation is requested, allowing Runtime to drop an in-flight external operation and stop the execution attempt.

Source

fn clear_cancel<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, key: &'life1 ThreadKey, run_id: &'life2 RunId, ) -> Pin<Box<dyn Future<Output = Result<(), StoreError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Clears the cancellation signal after a run has settled.

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
