Struct StateProofVerifier 

pub struct StateProofVerifier;

State proof verifier for resource existence verification.

Implementations

impl StateProofVerifier

pub fn verify(proof: &StateProof, expected_root: &[u8]) -> bool

Verify a state proof against the accumulator root.

Arguments

• proof - The state proof to verify
• expected_root - The expected accumulator root hash

Returns

true if the proof is valid, false otherwise.

pub fn verify_resource_exists( address: [u8; 32], resource_type: &str, rpc: &dyn AptosRpc, ) -> AptosResult<bool>

Verify that a resource was NOT consumed (still exists).

This is used to check seal resources before consumption.

Arguments

• address - The account address
• resource_type - The resource type tag
• rpc - RPC client for fetching state

Returns

true if the resource exists and has not been consumed.

pub fn verify_resource_consumed( address: [u8; 32], resource_type: &str, rpc: &dyn AptosRpc, ) -> AptosResult<bool>

Verify that a resource has been consumed (no longer exists).

This is used to verify seal consumption after publishing.
