Trait ComponentMetadataCatalog 

pub trait ComponentMetadataCatalog: Send + Sync {
    // Required methods
    fn get_metadata(&self, scheme: &str) -> Option<ComponentMetadata>;
    fn schemes(&self) -> Vec<String>;
    fn all_metadata(&self) -> Vec<ComponentMetadata>;

    // Provided method
    fn query_capabilities(
        &self,
        query: &CapabilityQuery,
    ) -> Vec<ComponentMetadata> { ... }
}

Query interface for component metadata at runtime.

Implementations store ComponentMetadata entries keyed by URI scheme and provide lookup and capability-filtering operations.

Required Methods

fn get_metadata(&self, scheme: &str) -> Option<ComponentMetadata>

Look up metadata for a component by its URI scheme.

fn schemes(&self) -> Vec<String>

Return all schemes that have registered metadata.

fn all_metadata(&self) -> Vec<ComponentMetadata>

Return metadata for all registered components.

Provided Methods

fn query_capabilities(&self, query: &CapabilityQuery) -> Vec<ComponentMetadata>

Filter components by capability query. Returns all metadata entries whose capabilities match every field in the query.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
