Struct Step 

pub struct Step {
    pub id: String,
    pub component: Component,
    pub on_error: Option<ErrorAction>,
    pub input: ValueExpr,
    pub must_execute: Option<bool>,
    pub metadata: HashMap<String, Value>,
}

A step in a workflow that executes a component with specific arguments.

Note: Step output schemas are stored in the flow’s types.steps field, not on individual steps. This allows for shared $defs and avoids duplication.

Fields

id: String

Identifier for the step

component: Component

The component to execute in this step

on_error: Option<ErrorAction>

input: ValueExpr

Arguments to pass to the component for this step

must_execute: Option<bool>

If true, this step must execute even if its output is not used by the workflow output. Useful for steps with side effects (e.g., writing to databases, sending notifications).

metadata: HashMap<String, Value>

Extensible metadata for the step that can be used by tools and frameworks.

Implementations

impl Step

pub fn builder<S>(id: S) -> StepBuilder

where S: Into<String>,

Create a new StepBuilder with the given ID.

impl Step

pub fn on_error(&self) -> Option<&ErrorAction>

pub fn on_error_or_default(&self) -> ErrorAction

Get the effective error action, applying the default if none is specified.

pub fn must_execute(&self) -> bool

Check if this step must execute, treating None as false (the default).

Trait Implementations

impl Clone for Step

fn clone(&self) -> Step

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Step

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

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

fn deserialize<__D>( __deserializer: __D, ) -> Result<Step, <__D as Deserializer<'de>>::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.

impl PartialEq for Step

fn eq(&self, other: &Step) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Step

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
