Struct Step 

pub struct Step {
    pub intent: String,
    pub precondition: Option<Condition>,
    pub action: Action,
    pub fallback: Option<Action>,
    pub expect: Condition,
    pub timeout: Option<Duration>,
    pub retry: RetryPolicy,
    pub on_failure: OnFailure,
    pub on_success: OnSuccess,
}

A single automation intent: execute an action, then wait for an expected UI state.

Fields

intent: String

Human-readable label shown in logs, e.g. "click the Save button".

precondition: Option<Condition>

Optional guard evaluated before the action. If false, the step is skipped (not an error). Useful for conditional steps such as “dismiss dialog if it appeared”.

action: Action

The UI action to perform: click, type text, press a key, close a window, etc.

fallback: Option<Action>

Optional fallback action run when expect times out on the primary action. After the fallback runs, expect is re-polled once with a fresh timeout. If it succeeds, the step succeeds; otherwise on_failure decides what happens.

expect: Condition

Condition that must become true after the action for the step to succeed. Polled every 100 ms until satisfied or the timeout elapses.

timeout: Option<Duration>

Maximum time to wait for expect to become true. Overrides the workflow default. Accepts duration strings such as "5s", "300ms", "2m".

retry: RetryPolicy

Retry policy on timeout. Overrides the workflow default. Default: none — falls back to the workflow-level default.

on_failure: OnFailure

What to do when this step fails (expect condition times out, or fallback also fails). Default: abort — propagate the error and stop the phase.

on_success: OnSuccess

What to do immediately after this step succeeds. Default: continue — proceed to the next step.

Trait Implementations

impl<'de> Deserialize<'de> for Step

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for Step

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.
