Struct Contract

pub struct Contract(/* private fields */);

Deployable representation of a contract code.

Implementations

impl Contract

pub const EMPTY_CONTRACT_ID: ContractId = _

The ContractId of the contract with empty bytecode, zero salt, and empty state root.

pub fn len(&self) -> usize

Number of bytes in the contract’s bytecode

pub fn is_empty(&self) -> bool

Check if the contract’s bytecode is empty

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) -> Bytes32

where B: AsRef<[u8]>,

Calculate the code root from a contract.

pub fn initial_state_root<'a, I>(storage_slots: I) -> Bytes32

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

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.

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

Performs the conversion.

impl TryFrom<&Transaction> for Contract

type Error = ValidityError

The type returned in the event of a conversion error.

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

Performs the conversion.
