Struct AASigned 

pub struct AASigned {
    tx: TempoTransaction,
    signature: TempoSignature,
    hash: OnceLock<FixedBytes<32>>,
}

A transaction with an AA signature and hash seal.

This wraps a TempoTransaction transaction with its multi-signature-type signature (secp256k1, P256, Webauthn, Keychain) and provides a cached transaction hash.

Fields

tx: TempoTransaction

signature: TempoSignature

hash: OnceLock<FixedBytes<32>>
