Expand description

ProcedureManager executes Procedure submitted to it.

Required Methods§

Source

fn register_loader( &self, name: &str, loader: BoxedProcedureLoader, ) -> Result<()>

Registers loader for specific procedure type name.

Source

fn start<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Starts the background GC task.

Recovers unfinished procedures and reruns them.

Callers should ensure all loaders are registered.

Source

fn stop<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Stops the background GC task.

Source

fn submit<'life0, 'async_trait>( &'life0 self, procedure: ProcedureWithId, ) -> Pin<Box<dyn Future<Output = Result<Watcher>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Submits a procedure to execute.

Returns a Watcher to watch the created procedure.

Source

fn procedure_state<'life0, 'async_trait>( &'life0 self, procedure_id: ProcedureId, ) -> Pin<Box<dyn Future<Output = Result<Option<ProcedureState>>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Query the procedure state.

Returns Ok(None) if the procedure doesn’t exist.

Source

fn procedure_watcher(&self, procedure_id: ProcedureId) -> Option<Watcher>

Returns a Watcher to watch ProcedureState of specific procedure.

Source

fn list_procedures<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<Vec<ProcedureInfo>>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Returns the details of the procedure.
