Struct Capability 

pub struct Capability {
    pub id: [u8; 16],
    pub issuer: Did,
    pub bearer: Did,
    pub scope: Scope,
    pub ops: Ops,
    pub expiry: Option<u64>,
    pub budget_micro_mata: Option<u64>,
    pub delegation_depth: u8,
}

A grant of access from an issuer to a bearer.

Fields

id: [u8; 16]

Unique grant id (the revocation key).

issuer: Did

Who granted this (the owner / a delegating bearer).

bearer: Did

Who may use it (a human or an AI agent).

scope: Scope

What it applies to.

ops: Ops

Which operations it allows.

expiry: Option<u64>

Optional expiry (unix seconds); None = until revoked.

budget_micro_mata: Option<u64>

Optional spend cap in micro-$MATA (the metering hook for M8).

delegation_depth: u8

How many more times this may be re-delegated (0 = not delegable).

Implementations

impl Capability

pub fn grant( issuer: impl Into<Did>, bearer: impl Into<Did>, scope: Scope, ops: Ops, ) -> Result<Capability, AccessError>

Mint a fresh capability with a random id, no expiry/budget, non-delegable. Refine with the builder methods.

pub fn with_expiry(self, unix_seconds: u64) -> Capability

pub fn with_budget(self, micro_mata: u64) -> Capability

pub fn with_delegation_depth(self, depth: u8) -> Capability
