Enum Error 

pub enum Error {
    NonceAlreadyUsed = 37_000,
    AuthorizationExpired = 37_001,
    AuthorizationNotYetValid = 37_002,
    InvalidSignature = 37_003,
    InvalidPublicKey = 37_004,

}

Errors raised by CEP-3009 authorization operations.

Variants

NonceAlreadyUsed = 37_000

The (from, nonce) pair has already been consumed by a transfer or burned by a cancel. Authorizations are single-use.

AuthorizationExpired = 37_001

The current block time is past valid_before — the authorization has expired.

AuthorizationNotYetValid = 37_002

The current block time is at or before valid_after — the authorization is not yet in its validity window.

InvalidSignature = 37_003

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

InvalidPublicKey = 37_004

The supplied public_key does not hash to the declared from / authorizer address. Guards against using a valid signature from a different keypair to move someone else’s tokens or burn their nonce.

InvalidCaller = 37_005

receive_with_authorization was submitted by an account other than to. See the module-level docs for why this restriction exists.

AuthorizationUsed = 37_006

Attempted to cancel an authorization whose (authorizer, nonce) pair has already been consumed.

InvalidNonceLength = 37_007

The supplied nonce is not exactly 32 bytes. ERC-3009 nonces are bytes32; the EIP-712 digest only covers 32 bytes, so accepting a shorter or longer nonce would let an attacker craft length aliases that share a digest (and thus a signature) while occupying distinct replay-protection storage keys.
