Enum chain_impl_mockchain::transaction::Witness

pub enum Witness {
    Utxo(SpendingSignature<WitnessUtxoData>),
    Account(SpendingCounter, Witness),
    OldUtxo(PublicKey<Ed25519>, [u8; 32], Signature<WitnessUtxoData, Ed25519>),
    Multisig(SpendingCounter, Witness),
}

Structure that proofs that certain user agrees with some data. This structure is used to sign Transaction and get SignedTransaction out.

It’s important that witness works with opaque structures and may not know the contents of the internal transaction.

Variants

Utxo(SpendingSignature<WitnessUtxoData>)

Account(SpendingCounter, Witness)

OldUtxo(PublicKey<Ed25519>, [u8; 32], Signature<WitnessUtxoData, Ed25519>)

Multisig(SpendingCounter, Witness)

Implementations

impl Witness

pub fn new_utxo_data( block0: &HeaderId, sign_data_hash: &TransactionSignDataHash ) -> WitnessUtxoData

Creates new Witness value.

pub fn new_utxo<F>( block0: &HeaderId, sign_data_hash: &TransactionSignDataHash, sign: F ) -> Selfwhere F: FnOnce(&WitnessUtxoData) -> Signature<WitnessUtxoData, Ed25519>,

pub fn new_old_utxo_data( block0: &HeaderId, sign_data_hash: &TransactionSignDataHash ) -> WitnessUtxoData

pub fn new_old_utxo<F>( block0: &HeaderId, sign_data_hash: &TransactionSignDataHash, sign: F, some_bytes: &[u8; 32] ) -> Selfwhere F: FnOnce(&WitnessUtxoData) -> (PublicKey<Ed25519>, Signature<WitnessUtxoData, Ed25519>),

pub fn new_account_data( block0: &HeaderId, sign_data_hash: &TransactionSignDataHash, spending_counter: SpendingCounter ) -> WitnessAccountData

pub fn new_account<F>( block0: &HeaderId, sign_data_hash: &TransactionSignDataHash, spending_counter: SpendingCounter, sign: F ) -> Selfwhere F: FnOnce(&WitnessAccountData) -> Witness,

pub fn to_bytes(&self) -> Vec<u8>

Trait Implementations

impl Arbitrary for Witness

fn arbitrary<G: Gen>(g: &mut G) -> Self

fn shrink(&self) -> Box<dyn Iterator<Item = Self>, Global>

impl Clone for Witness

fn clone(&self) -> Witness

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Witness

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl DeserializeFromSlice for Witness

fn deserialize_from_slice(codec: &mut Codec<&[u8]>) -> Result<Self, ReadError>

fn deserialize_validate_from_slice( codec: &mut Codec<&[u8]> ) -> Result<(), ReadError>

impl Display for Witness

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq<Witness> for Witness

fn eq(&self, rhs: &Self) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Witness

fn serialized_size(&self) -> usize

Default implementation, not efficient, not recommended to use it

fn serialize<W: Write>(&self, codec: &mut Codec<W>) -> Result<(), WriteError>

fn serialize_as_vec(&self) -> Result<Vec<u8, Global>, WriteError>

Convenience method to serialize into a byte vector.
