Struct WorkflowDefinitions 

pub struct WorkflowDefinitions { /* private fields */ }

The pure half of a set of workflows: definitions only.

Built by WorkflowRegistry::definitions, or from erased definitions directly when there is no registry — a corpus replayed against a projector has states in hand and no executor at all.

Implementations

impl WorkflowDefinitions

pub fn new() -> Self

An empty set.

pub fn with(self, definition: Arc<dyn ErasedWorkflow>) -> Self

Adds one definition, keyed by ErasedWorkflow::key. A repeated key replaces the previous entry.

pub fn get(&self, key: &WorkflowKey) -> Option<&Arc<dyn ErasedWorkflow>>

Looks a definition up.

pub fn require( &self, key: &WorkflowKey, ) -> Result<&Arc<dyn ErasedWorkflow>, ErasureError>

Looks a definition up, failing when unknown.

Errors

ErasureError::UnknownWorkflow when the key is not present.

pub fn contains(&self, key: &WorkflowKey) -> bool

Returns true when the key is present.

pub fn keys(&self) -> impl Iterator<Item = &WorkflowKey>

Keys in insertion order.

pub fn iter(&self) -> impl Iterator<Item = &Arc<dyn ErasedWorkflow>>

Definitions in insertion order.

pub fn len(&self) -> usize

Number of definitions.

pub fn is_empty(&self) -> bool

Returns true when empty.
