Trait TrustRootResolver 

pub trait TrustRootResolver {
    // Required method
    fn trust_root_scope_hash(&self, issuer: &PublicKey) -> Option<ScopeHash>;
}

Resolver returning the trust-root scope hash bound to a given issuer public key. Kernels supply this so the verifier can bind attenuation_proof.parent_scope_hash to the issuing CA’s authority hash on direct-issue attenuated tokens.

Required Methods

fn trust_root_scope_hash(&self, issuer: &PublicKey) -> Option<ScopeHash>

Resolve the trust-root scope hash for issuer, returning None when the issuer has no registered authority hash. The verifier treats None as a fail-closed deny for attenuated tokens that require chain binding.

Dyn Compatibility

This trait is dyn compatible.

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