Typed metadata for multimodal artifacts. This enum provides strongly-typed metadata schemas for different artifact types. It can be serialized to/from the generic metadata JSONB field.

Implementations

impl ArtifactMetadata

pub fn to_json(&self) -> Value

Convert to a generic JSON value for storage in the metadata field.

pub fn from_json(value: &Value) -> Option<Self>

Try to parse from a generic JSON value.

Trait Implementations

impl Clone for ArtifactMetadata

fn clone(&self) -> ArtifactMetadata

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl ComposeSchema for ArtifactMetadata

fn compose(generics: Vec<RefOr<Schema>>) -> RefOr<Schema>

impl Debug for ArtifactMetadata

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ArtifactMetadata

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ArtifactMetadata

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl ToSchema for ArtifactMetadata

fn name() -> Cow<'static, str>

Return name of the schema.

fn schemas(schemas: &mut Vec<(String, RefOr<Schema>)>)

Implement reference [utoipa::openapi::schema::Schema]s for this type.
