    fn name(&self) -> &'static str;
    fn create(&self, runtime: KhiveRuntime) -> Box<dyn PackRuntime>;

Required Methods

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

Canonical lowercase name for this pack (e.g. "kg", "gtd").

fn create(&self, runtime: KhiveRuntime) -> Box<dyn PackRuntime>

Create a new pack instance for the given runtime.

Provided Methods

fn requires(&self) -> &'static [&'static str]

Names of packs that must be loaded before this one.

Defaults to empty so pack crates that have no dependencies compile without changes. PackRegistry::register_packs validates that every name listed here is present in the caller’s explicit pack list — absent dependencies are a boot error, not silently auto-added.

fn intentionally_verbless(&self) -> bool

Whether this pack intentionally exposes no top-level MCP verbs.

Defaults to false so a declared pack whose runtime contributes no Visibility::Verb handlers fails at registration instead of silently disappearing from the served surface. Vocabulary- or ontology-only packs must opt in explicitly.

fn create_install(&self, runtime: KhiveRuntime) -> PackInstall

Build the full installation bundle for this pack: runtime, optional resolver, optional dispatch hook.

Defaults to composing create and create_resolver with no dispatch hook, so existing factories compile unchanged. Packs whose dispatch hook must observe the same instance as the runtime (e.g. brain) override this method instead of create, since the default would otherwise require two independent instances to share state.

fn create_resolver( &self, _runtime: KhiveRuntime, ) -> Option<Box<dyn PackByIdResolver>>

Optionally create a PackByIdResolver for this pack.

Packs that own private SQL tables implement this to hook into get(id) and delete(id). Defaults to None so existing packs compile without changes.

Dyn Compatibility

This trait is dyn compatible.

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