type TargetKey: Debug + Clone + Serialize + DeserializeOwned + Eq + Hash + Send + Sync

type TargetSpec: DeserializeOwned + Send + Sync

type Spec: DeserializeOwned + Send + Sync

type SetupKey: Debug + Clone + Serialize + DeserializeOwned + Eq + Hash + Send + Sync

type SetupState: Debug + Clone + Serialize + DeserializeOwned + Send + Sync

type SetupChange: AttachmentSetupChange + Send + Sync

Required Methods

fn name(&self) -> &str

fn get_state( &self, target_name: &str, target_spec: &Self::TargetSpec, attachment_spec: Self::Spec, ) -> Result<TypedTargetAttachmentState<Self>>

fn diff_setup_states<'life0, 'life1, 'life2, 'life3, 'async_trait>( &'life0 self, target_key: &'life1 Self::TargetKey, attachment_key: &'life2 Self::SetupKey, new_state: Option<Self::SetupState>, existing_states: CombinedState<Self::SetupState>, context: &'life3 FlowInstanceContext, ) -> Pin<Box<dyn Future<Output = Result<Option<Self::SetupChange>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, 'life3: 'async_trait,

Provided Methods

fn deserialize_setup_key(key: Value) -> Result<Self::SetupKey>

Deserialize the setup key from a JSON value. You can override this method to provide a custom deserialization logic, e.g. to perform backward compatible deserialization.

fn register(self, registry: &mut ExecutorFactoryRegistry) -> Result<()>

where Self: Sized,

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
