Struct WorkflowRegistry 

pub struct WorkflowRegistry { /* private fields */ }

Heterogeneous set of workflows keyed by WorkflowKey (spec §8.3).

Implementations

impl WorkflowRegistry

pub fn builder() -> WorkflowRegistryBuilder

Starts a builder.

pub fn get(&self, key: &WorkflowKey) -> Option<&RegisteredWorkflow>

Looks a workflow up.

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

Looks a workflow up, failing when unknown.

pub fn check_version( &self, key: &WorkflowKey, found: &WorkflowVersion, ) -> Result<(), ErasureError>

Checks that found is the registered version of key.

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

Returns true when the key is registered.

pub fn iter(&self) -> impl Iterator<Item = &RegisteredWorkflow>

Iterates registrations in registration order.

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

Registered keys in registration order.

pub fn len(&self) -> usize

Number of workflows.

pub fn is_empty(&self) -> bool

Returns true when empty.

pub fn definitions(&self) -> WorkflowDefinitions

The definitions alone: everything pure, no executor of any kind.

Projection, the act catalog, act compilation, command policy, command validation and receipts are all here, and none of them reads or writes anything. A caller handed this cannot even load a case, which is the right shape for a path that is given the state instead.

pub fn read_only(&self) -> WorkflowReadRegistry

The registry with the write half of every executor removed: the pure definitions plus the loading half of each executor.

This is what the plan-only turn path is built on. Nothing in the returned value can execute a batch, so a planning run cannot mutate a case however it is refactored.

Trait Implementations

impl Clone for WorkflowRegistry

fn clone(&self) -> WorkflowRegistry

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WorkflowRegistry

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

Formats the value using the given formatter.

impl Default for WorkflowRegistry

fn default() -> WorkflowRegistry

Returns the “default value” for a type.
