Struct SkillRegistry 

pub struct SkillRegistry { /* private fields */ }

The broker’s registry of admitted skills.

Registration is the trust boundary: the broker takes an Admission (already verified by ) and the skill’s code bytes, pins the code hash, and only then lists the skill. Every lookup can re-verify the code against the pinned hash to detect drift.

Implementations

impl SkillRegistry

pub fn new() -> Self

Create an empty registry.

pub fn register( &mut self, admission: Admission, code: &[u8], ) -> Result<SkillId, Error>

Register an admitted skill with its code bytes.

The code hash is computed from the actual bytes and pinned. If a skill with the same id is already registered, registration is refused — even if the code hash matches. Silent re-registration would let a caller swap a skill’s code without any signal; the explicit unregister + register sequence is the only update path (both are auditable broker operations).

Errors

Returns Error::AlreadyRegistered if the id is already registered.

pub fn unregister(&mut self, id: &SkillId) -> bool

Remove a skill from the registry by id.

This is the explicit half of the update path: unregister then register replaces a skill’s code with a clear audit trail. Returns true if a skill was removed, false if the id was not registered.

pub fn get(&self, id: &SkillId) -> Option<&RegisteredSkill>

Look up a registered skill by id.

pub fn verify_code(&self, id: &SkillId, code: &[u8]) -> Result<(), Error>

Verify code bytes against the pinned hash for a registered skill.

Call this at load time and at call time: if the code on disk (or presented by the cell) doesn’t match the pinned hash, the skill has drifted and must be refused.

Errors

Returns Error::UnknownSkill if the id is not registered. Returns Error::IdentityDrift if the hash doesn’t match.

pub fn list(&self) -> Vec<SkillId>

List all registered skill ids.

pub fn len(&self) -> usize

The number of registered skills.

pub fn is_empty(&self) -> bool

Whether the registry is empty.
