Struct ProofVerifier 

pub struct ProofVerifier { /* private fields */ }

Verifies proof tokens for store mutations.

Implementations

impl ProofVerifier

pub fn new(policy: ProofPolicy) -> Self

Creates a new proof verifier with the given policy.

pub const fn policy(&self) -> &ProofPolicy

Returns the proof policy.

pub fn verify( &mut self, proof: &ProofToken, expected_mutation_hash: &[u8; 32], current_time_ns: u64, capability: &Capability, ) -> Result<ProofAttestation>

Verifies a proof token for a mutation.

Arguments

• proof - The proof token to verify
• expected_mutation_hash - Hash of the mutation being authorized
• current_time_ns - Current time in nanoseconds
• capability - The capability being used (must have PROVE right)

Returns

On success, returns a ProofAttestation to be logged. On failure, returns ProofRejected.

pub const fn verifier_version(&self) -> u32

Returns the verifier version.

pub const fn nonce_tracker(&self) -> &NonceTracker

Returns the nonce tracker.

Trait Implementations

impl Default for ProofVerifier

fn default() -> Self

Returns the “default value” for a type.
