Struct spl_token_2022::extension::confidential_transfer::instruction::transfer::without_fee::TransferData

#[repr(C)]
pub struct TransferData {
    pub context: TransferProofContext,
    pub proof: TransferProof,
}

The instruction data that is needed for the ProofInstruction::VerifyTransfer instruction.

It includes the cryptographic proof as well as the context data information needed to verify the proof.

Fields

context: TransferProofContext

The context data for the transfer proof

proof: TransferProof

Zero-knowledge proofs for Transfer

Implementations

impl TransferData

pub fn new( transfer_amount: u64, _: (u64, &ElGamalCiphertext), source_keypair: &ElGamalKeypair, _: (&ElGamalPubkey, &ElGamalPubkey), ) -> Result<TransferData, ProofGenerationError>

pub fn decrypt_amount( &self, role: Role, sk: &ElGamalSecretKey, ) -> Result<u64, InstructionError>

Decrypts transfer amount from transfer data
