Expand description

ContextProvider provides information about procedures in the ProcedureManager.

Required Methods§

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.

Source

fn try_put_poison<'life0, 'life1, 'async_trait>( &'life0 self, key: &'life1 PoisonKey, procedure_id: ProcedureId, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Try to put a poison key for a procedure.

This method is used to mark a resource as being operated on by a procedure. If the poison key already exists with a different value, the operation will fail.
