Struct WorkflowInvocation 

#[non_exhaustive]
pub struct WorkflowInvocation {
    pub run_id: String,
    pub spec: WorkflowSpec,
    pub input: JsonValue,
    pub history: Vec<FlowEventEnvelope>,
}

Workflow replay request passed to a runtime implementation.

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.

run_id: String

Durable identifier of the workflow run being replayed.

spec: WorkflowSpec

Workflow definition recorded when the run was created.

input: JsonValue

Original workflow input.

history: Vec<FlowEventEnvelope>

Complete persisted event history in sequence order.

Implementations

impl WorkflowInvocation

pub fn new( run_id: impl Into<String>, spec: WorkflowSpec, input: JsonValue, history: Vec<FlowEventEnvelope>, ) -> Self

Create a workflow invocation from its complete durable replay input.

pub fn context(&self) -> WorkflowContext<'_>

Build a deterministic helper view over this workflow invocation.

pub fn input_as<T>(&self) -> Result<T>

where T: DeserializeOwned,

Decode the workflow input into a host-defined serde type.
