}

Inputs for running a child workflow from a ChildWorkflowRunner implementation.

Pairs with ChildWorkflowContext (projected from the parent run) to supply fields that the parent context does not carry. Pass to FlowEngine::run_child.

Note on child_runner: pass Some(Arc::clone(&self_runner)) from a ChildWorkflowRunner::execute_child implementation so grandchild workflow calls work. A None value produces a child run that cannot fan out further.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

workflow_run_id: String

The pre-created child run ID (from persistence).

persistence: Arc<dyn WorkflowPersistence>

action_registry: Arc<ActionRegistry>

item_provider_registry: Arc<ItemProviderRegistry>

script_env_provider: Arc<dyn ScriptEnvProvider>

child_runner: Option<Arc<dyn ChildWorkflowRunner>>

Re-inject the same runner for grandchild support; None disables further nesting.

schema_resolver: Option<Arc<dyn Fn(&str) -> Result<OutputSchema> + Send + Sync>>

as_identity: Option<String>

Maps to ExecutionState::default_as_identity.

depth: u32

cancellation: CancellationToken

target_label: Option<String>

triggered_by_hook: bool

inputs_override: Option<HashMap<String, String>>

When Some, replaces the parent context’s inputs; when None, parent inputs flow through.

Implementations

impl ChildRunInput

pub fn new( workflow_run_id: String, persistence: Arc<dyn WorkflowPersistence>, action_registry: Arc<ActionRegistry>, item_provider_registry: Arc<ItemProviderRegistry>, script_env_provider: Arc<dyn ScriptEnvProvider>, depth: u32, cancellation: CancellationToken, ) -> Self

Construct a ChildRunInput with required fields; all optional/defaultable fields are zeroed.

Use direct field assignment (input.as_identity = Some(...)) to set any optional fields.
