Struct Registry 

pub struct Registry { /* private fields */ }

Registry that stores components by their URI scheme.

Also harvests and indexes ComponentMetadata for each registered component, so the metadata can be queried through a ComponentMetadataCatalog without re-invoking the component.

Implementations

impl Registry

pub fn new() -> Self

Create an empty registry.

pub fn register(&mut self, component: Arc<dyn Component>)

Register a component. Replaces any existing component with the same scheme.

Harvests the component’s ComponentMetadata and indexes it by scheme in parallel with the component insertion. Validates that the metadata’s scheme matches the component’s scheme, normalizing on mismatch with a warning log.

pub fn get(&self, scheme: &str) -> Option<Arc<dyn Component>>

Look up a component by scheme.

pub fn get_or_err(&self, scheme: &str) -> Result<Arc<dyn Component>, CamelError>

Look up a component by scheme, returning an error if not found.

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

Look up harvested metadata for a component by scheme.

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

Return metadata for every registered component.

pub fn metadata_schemes(&self) -> Vec<String>

Return the schemes of every registered component’s metadata.

pub fn len(&self) -> usize

Returns the number of registered components.

pub fn is_empty(&self) -> bool

Returns true if no components are registered.

Trait Implementations

impl Default for Registry

fn default() -> Self

Returns the “default value” for a type.
