pub const fn is_variable(&self) -> bool

pub const fn is_contract(&self) -> bool

pub const fn is_contract_created(&self) -> bool

pub fn message_id(
    sender: &Address,
    recipient: &Address,
    nonce: &Bytes32,
    amount: Word,
    data: &[u8]
) -> MessageId

pub fn message_nonce(txid: &Bytes32, idx: Word) -> Bytes32

pub fn message_digest(data: &[u8]) -> Bytes32

pub fn prepare_init_script(&mut self) -> Result<()>

Prepare the output for VM initialization for script execution

pub fn prepare_init_predicate(&mut self)

Prepare the output for VM initialization for predicate verification

impl Output

pub fn validate(
    &self,
    index: usize,
    inputs: &[Input]
) -> Result<(), ValidationError>

Validate the output of the transaction.

This function is stateful - meaning it might validate a transaction during VM initialization, but this transaction will no longer be valid in post-execution because the VM might mutate the message outputs, producing invalid transactions.

Trait Implementations

impl Clone for Output

fn clone(&self) -> Output

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Output

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

Formats the value using the given formatter.

impl Default for Output

fn default() -> Self

Returns the “default value” for a type.

impl From<&Output> for OutputRepr

fn from(o: &Output) -> Self

Converts to this type from the input type.

impl From<&mut Output> for OutputRepr

fn from(o: &mut Output) -> Self

Converts to this type from the input type.

impl Hash for Output

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher, 

Feeds a slice of this type into the given Hasher.

impl PartialEq<Output> for Output

fn eq(&self, other: &Output) -> bool

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

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

This method tests for !=.

impl Read for Output

fn read(&mut self, buf: &mut [u8]) -> Result<usize>

Pull some bytes from this source into the specified buffer, returning how many bytes were read.

fn read_vectored(&mut self, bufs: &mut [IoSliceMut<'_>]) -> Result<usize, Error>

Like read, except that it reads into a slice of buffers.

fn is_read_vectored(&self) -> bool

🔬 This is a nightly-only experimental API. (can_vector)

Determines if this Reader has an efficient read_vectored implementation.

fn read_to_end(&mut self, buf: &mut Vec<u8, Global>) -> Result<usize, Error>

Read all bytes until EOF in this source, placing them into buf.

fn read_to_string(&mut self, buf: &mut String) -> Result<usize, Error>

Read all bytes until EOF in this source, appending them to buf.

fn read_exact(&mut self, buf: &mut [u8]) -> Result<(), Error>

Creates an adapter which will read at most limit bytes from it.

impl SizedBytes for Output

fn serialized_size(&self) -> usize

Return the expected serialized size for an instance of the type.

impl Write for Output

fn write(&mut self, buf: &[u8]) -> Result<usize>
