Trait Service

    // Provided methods
    fn name(&self) -> &'static str { ... }
    fn init(
        &self,

Provided Methods

fn name(&self) -> &'static str

fn init( &self, _ctx: &Arc<Context>, ) -> Pin<Box<dyn Future<Output = Result<Option<Box<dyn Disposable>>, CordisError>> + Send + '_>>

fn check(&self) -> bool

Availability predicate for this service instance.

The kernel consumes check() at every point where a freshly built instance meets the graph:

• crate::RegistryService::register — after the plugin factory produces the service and BEFORE it is provided; a false verdict rests the fiber as inspectable Failed { error: "availability predicate rejected service" } instead of Active. Registration is non-throwing: register-before-ready is a supported transient that later refreshes converge.
• crate::Context::plugin — after init; a false verdict leaves the provided value in place but rests the fiber as Inactive (the historical behavior).

It is NOT consulted on untyped store reads (Context::get): the store holds type-erased values, so per-read checks would need downcasting machinery that no consumer has asked for. Services whose availability can change AFTER registration (circuit breakers, feature gates) must drive their dependents by re-providing / notifying instead of relying on spontaneous re-checks.

Dyn Compatibility

This trait is dyn compatible.

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