Struct SchemaArtifact 

pub struct SchemaArtifact {
    pub id: String,
    pub name: String,
    pub version: String,
    pub body: Value,
}

A content-addressed schema or reducer artifact.

The id is derived from the canonical serialization of (name, version, body). Equal artifacts have equal ids; different artifacts have ids that differ except with negligible probability under SHA-256.

Fields

id: String

Content-addressed id, prefixed with vsa_ (Vela Schema Artifact). This is H(canonical(name, version, body)).

name: String

Human-readable name (e.g. vela.event.finding_asserted).

version: String

Semver-style version string (e.g. v0.1).

body: Value

Body of the artifact: the actual schema or reducer specification, kept as a JSON value to avoid committing to any one schema language at the substrate layer.

Implementations

impl SchemaArtifact

pub fn new( name: impl Into<String>, version: impl Into<String>, body: Value, ) -> Result<Self, String>

Build a new artifact, computing the content-addressed id from the canonical serialization of (name, version, body).

pub fn derive_id( name: &str, version: &str, body: &Value, ) -> Result<String, String>

Derive the content-addressed id without constructing an artifact. Useful for verifying that a stored artifact’s id matches its content.

pub fn verify_id(&self) -> Result<(), String>

Verify that this artifact’s stored id matches the id derived from its content.

Trait Implementations

impl Clone for SchemaArtifact

fn clone(&self) -> SchemaArtifact

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SchemaArtifact

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SchemaArtifact

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for SchemaArtifact

fn eq(&self, other: &SchemaArtifact) -> 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 SchemaArtifact

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
