Implementations

impl Schema

pub fn cid(&self) -> String

Computes the content-addressed identifier for this schema.

pub fn identity_hash(&self) -> String

Computes a structural fingerprint (ignoring name/version).

pub fn equal(&self, other: &Schema) -> bool

Returns true if two schemas have the same CID.

pub fn structurally_equal(&self, other: &Schema) -> bool

Returns true if two schemas have the same structure.

impl Schema

pub fn action_for_event(&self, event_id: &str) -> Option<&Action>

pub fn input_arcs(&self, action_id: &str) -> Vec<&Arc>

Returns all arcs flowing into an action.

pub fn output_arcs(&self, action_id: &str) -> Vec<&Arc>

Returns all arcs flowing out of an action.

pub fn data_states(&self) -> Vec<&State>

impl Schema

pub fn validate(&self) -> Result<()>

Validates the schema for structural correctness.
