Struct fuel_tx::Contract

pub struct Contract(_);

Deployable representation of a contract code.

Implementations

impl Contract

pub fn root(&self) -> Bytes32

Calculate the code root of the contract, using Self::root_from_code.

pub fn root_from_code<B>(bytes: B) -> Bytes32where B: AsRef<[u8]>,

Calculate the code root from a contract.

pub fn initial_state_root<'a, I>(storage_slots: I) -> Bytes32where I: Iterator<Item = &'a StorageSlot>,

Calculate the root of the initial storage slots for this contract

pub fn default_state_root() -> Bytes32

The default state root value without any entries

pub fn id( &self, salt: &Salt, root: &Bytes32, state_root: &Bytes32 ) -> ContractId

Calculate and return the contract id, provided a salt, code root and state root.

Trait Implementations

impl AsMut<[u8]> for Contract

fn as_mut(&mut self) -> &mut [u8]

Converts this type into a mutable reference of the (usually inferred) input type.

impl AsRef<[u8]> for Contract

fn as_ref(&self) -> &[u8]

Converts this type into a shared reference of the (usually inferred) input type.

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 From<&[u8]> for Contract

fn from(c: &[u8]) -> Self

Converts to this type from the input type.

impl From<&mut [u8]> for Contract

fn from(c: &mut [u8]) -> Self

Converts to this type from the input type.

impl From<Contract> for Vec<u8>

fn from(c: Contract) -> Vec<u8>

Converts to this type from the input type.

impl From<Vec<u8, Global>> for Contract

fn from(c: Vec<u8>) -> Self

Converts to this type from the input type.

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<Contract> for Contract

fn eq(&self, other: &Contract) -> 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 TryFrom<&Create> for Contract

type Error = CheckError

The type returned in the event of a conversion error.

fn try_from(tx: &Create) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<&Transaction> for Contract

type Error = CheckError

The type returned in the event of a conversion error.

fn try_from(tx: &Transaction) -> Result<Self, Self::Error>

Performs the conversion.

impl Eq for Contract

impl StructuralEq for Contract

impl StructuralPartialEq for Contract
