Struct Contract

pub struct Contract {
    pub utxo_id: UtxoId,
    pub balance_root: Bytes32,
    pub state_root: Bytes32,
    pub tx_pointer: TxPointer,
    pub contract_id: ContractId,
}

It is a full representation of the contract input from the specification: https://github.com/FuelLabs/fuel-specs/blob/master/src/tx-format/input.md#inputcontract.

The specification defines the layout of the Contract in the serialized form for the fuel-vm.

Fields

utxo_id: UtxoId

balance_root: Bytes32

state_root: Bytes32

tx_pointer: TxPointer

Pointer to transction that last modified the contract state.

contract_id: ContractId

Implementations

impl Contract

pub fn prepare_sign(&mut self)

The “Note” section from the specification: https://github.com/FuelLabs/fuel-specs/blob/master/src/tx-format/input.md#inputcontract.

Trait Implementations

impl Clone for Contract

fn clone(&self) -> Contract

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Contract

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

Formats the value using the given formatter.

impl Default for Contract

fn default() -> Contract

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Contract

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Deserialize for Contract

fn decode_static<I: Input + ?Sized>(buffer: &mut I) -> Result<Self, Error>

Decodes static part of Self from the buffer.

fn decode_dynamic<I: Input + ?Sized>( &mut self, buffer: &mut I, ) -> Result<(), Error>

Decodes dynamic part of the information from the buffer to fill Self. The default implementation does nothing. Dynamically-sized contains should override this.

fn decode<I>(buffer: &mut I) -> Result<Self, Error>

where I: Input + ?Sized,

Decodes Self from the buffer.

fn from_bytes(buffer: &[u8]) -> Result<Self, Error>

Helper method for deserializing Self from bytes.

impl Hash for Contract

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, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Contract

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl Serialize for Contract

fn size_static(&self) -> usize

Size of the static part of the serialized object, in bytes. Saturates to usize::MAX on overflow.

fn size_dynamic(&self) -> usize

Size of the dynamic part, in bytes. Saturates to usize::MAX on overflow.

fn encode_static<O: Output + ?Sized>(&self, buffer: &mut O) -> Result<(), Error>

Encodes staticly-sized part of Self.

fn encode_dynamic<O: Output + ?Sized>( &self, buffer: &mut O, ) -> Result<(), Error>

Encodes dynamically-sized part of Self. The default implementation does nothing. Dynamically-sized contains should override this.

fn size(&self) -> usize

Total size of the serialized object, in bytes. Saturates to usize::MAX on overflow.

fn encode<O>(&self, buffer: &mut O) -> Result<(), Error>

where O: Output + ?Sized,

Encodes Self into the buffer.

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

Encodes Self into bytes vector. Required known size.

impl Serialize for Contract

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Contract

impl StructuralPartialEq for Contract
