Enum Error 

pub enum Error {
    InvalidSignature = 36_000,
    PermitExpired = 36_001,
    InvalidPublicKey = 36_002,
}

Errors raised by CEP-2612 permit operations.

Variants

InvalidSignature = 36_000

Signature verification against the supplied public key failed, or the recomputed digest does not match what the signer signed (e.g. wrong value, nonce, spender, or deadline).

PermitExpired = 36_001

The current block time is past the deadline timestamp (a Unix timestamp in seconds, per the ERC-2612 convention). Permits with deadline == u64::MAX skip this check and never expire.

InvalidPublicKey = 36_002

The supplied public_key does not hash to the declared owner address. Guards against using a valid signature from a different keypair to approve on someone else’s behalf.
