Implementations

impl Output

pub const fn repr(&self) -> OutputRepr

pub const fn coin(to: Address, amount: u64, asset_id: AssetId) -> Output

pub const fn contract( input_index: u8, balance_root: Bytes32, state_root: Bytes32 ) -> Output

pub const fn change(to: Address, amount: u64, asset_id: AssetId) -> Output

pub const fn variable(to: Address, amount: u64, asset_id: AssetId) -> Output

pub const fn contract_created( contract_id: ContractId, state_root: Bytes32 ) -> Output

pub const fn asset_id(&self) -> Option<&AssetId>

pub const fn to(&self) -> Option<&Address>

pub const fn amount(&self) -> Option<u64>

pub const fn input_index(&self) -> Option<u8>

pub const fn balance_root(&self) -> Option<&Bytes32>

pub const fn state_root(&self) -> Option<&Bytes32>

pub const fn contract_id(&self) -> Option<&ContractId>

pub const fn is_coin(&self) -> bool

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_nonce(txid: &Bytes32, idx: u64) -> Nonce

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

pub fn prepare_init_script(&mut self)

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 check(&self, index: usize, inputs: &[Input]) -> Result<(), CheckError>

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<(), Error>

Formats the value using the given formatter.

impl Default for Output

fn default() -> Output

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Output

fn deserialize<__D>( __deserializer: __D ) -> Result<Output, <__D as Deserializer<'de>>::Error>where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl EnumCount for Output

const COUNT: usize = 5usize

impl Hash for Output

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

Feeds this value into the given Hasher.

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

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: &Rhs) -> bool

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

impl Read for Output

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

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>

Read the exact number of bytes required to fill buf.

fn read_buf(&mut self, buf: BorrowedCursor<'_>) -> Result<(), Error>

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

Pull some bytes from this source into the specified buffer.

fn read_buf_exact(&mut self, cursor: BorrowedCursor<'_>) -> Result<(), Error>

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

fn by_ref(&mut self) -> &mut Selfwhere Self: Sized,

Creates a “by reference” adaptor for this instance of Read.

fn bytes(self) -> Bytes<Self>where Self: Sized,

Transforms this Read instance to an Iterator over its bytes.

fn chain<R>(self, next: R) -> Chain<Self, R>where R: Read, Self: Sized,

Creates an adapter which will chain this stream with another.

fn take(self, limit: u64) -> Take<Self>where Self: Sized,

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

impl Serialize for Output

fn serialize<__S>( &self, __serializer: __S ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>where __S: Serializer,

Serialize this value into the given Serde serializer.
