Trait CapabilityInvoker 

pub trait CapabilityInvoker {
    // Required methods
    fn granted(&self) -> Vec<String>;
    fn invoke(&self, capability: &str, input: Value) -> CapabilityCallResult;

    // Provided methods
    fn is_granted(&self, capability: &str) -> bool { ... }
    fn describe(&self, capability: &str) -> Option<CapabilityDescription> { ... }
}

The boundary between this interpreter and the real world.

Implementations decide what a “capability” is: a direct Wasm component call, a broker proposal, or a test fixture. This crate never learns which.

Required Methods

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

Returns every capability identifier currently available to invoke.

fn invoke(&self, capability: &str, input: Value) -> CapabilityCallResult

Invokes one capability synchronously.

This is deliberately synchronous: this crate carries no async runtime dependency, and the calling binary’s model tool loop is untouched. An implementation that is asynchronous underneath bridges here itself, which is what dekopon-run does from its blocking task.

Provided Methods

fn is_granted(&self, capability: &str) -> bool

Reports whether one capability identifier is available, for dispatch-time lookup.

The default scans CapabilityInvoker::granted; override it when a cheaper lookup exists.

fn describe(&self, capability: &str) -> Option<CapabilityDescription>

Returns model-facing metadata for one capability, when the implementation has any.

Dyn Compatibility

This trait is dyn compatible.

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