Struct StepInvocation 

#[non_exhaustive]
pub struct StepInvocation {
    pub run_id: String,
    pub step_id: String,
    pub step_name: String,
    pub input: JsonValue,
    pub history: Vec<FlowEventEnvelope>,
}

Step execution 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 that scheduled the step.

step_id: String

Replay-stable identifier of this step invocation.

step_name: String

Host-defined step handler name.

input: JsonValue

Input supplied by the workflow command.

history: Vec<FlowEventEnvelope>

Complete persisted workflow history in sequence order.

Implementations

impl StepInvocation

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

Create a step invocation from its complete durable execution input.

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

where T: DeserializeOwned,

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

Trait Implementations
