What a step is.

Variants

Action

An action: an engine action (audit_log, emit_event, send_email, notify, send_notification, send_sms), or one the WorkflowDefinition performs.

Fields

action: String

The verb.

entity: Option<String>

The entity of an entity action.

id: Option<Tpl>

The record an update, delete or fetch is about.

params: Vec<(String, Tpl)>

The parameters, rendered when the step runs.

on_success: Outcome

What a success does.

on_timeout: Option<Outcome>

What a hand call that outlasts the step’s call_timeout does, instead of failing.

Transition

A state-machine verb on a record.

Fields

entity: String

The entity.

id: Tpl

The record.

verb: String

The verb.

params: Vec<(String, Tpl)>

Extra fields written with the move.

on_success: Outcome

What a success does.

Condition

A branch on conditions, in order.

Fields

branches: Vec<Branch>

The branches.

Wait

A durable wait.

Fields

event: Option<String>

The event waited for; None is a pure timer.

key: Vec<WaitKey>

The equalities that match an event to this instance.

timeout: Option<Dur>

How long to wait.

on_event: Option<Outcome>

What an event does.

on_timeout: Option<Outcome>

What the timeout does.

Terminal

An end.

Fields

status: Terminal

How it ends.

reason: Option<Tpl>

Why, for a person reading the log.

emit: Option<EmitSpec>

An event to stage.

compensate: bool

Run compensation after ending as failed.

result: Option<Tpl>

A value stored as context.result when the instance ends.
