A Component is a factory for Endpoints.

Each component handles a specific URI scheme (e.g. “timer”, “log”, “direct”).

Required Methods

fn scheme(&self) -> &str

The URI scheme this component handles (e.g., “timer”, “log”).

fn create_endpoint( &self, uri: &str, ctx: &dyn ComponentContext, ) -> Result<Box<dyn Endpoint>, CamelError>

Create an endpoint from a URI string.

Provided Methods

fn metadata(&self) -> ComponentMetadata

Declare this component’s metadata (URI options, capabilities, version).

Called once at registration time to harvest metadata into the catalog. Override to provide rich metadata; the default returns a minimal entry with just the scheme name.

fn start<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<(), CamelError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Start the component (e.g. connect to external systems).

Default: no-op, returns Ok(()).

fn stop<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<(), CamelError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Stop the component (e.g. release resources, close connections).

Default: no-op, returns Ok(()).

Dyn Compatibility

This trait is dyn compatible.

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