Struct Contract

pub struct Contract {
    pub input: Bytes,
    pub bytecode: Bytecode,
    pub hash: Option<B256>,
    pub target_address: Address,
    pub bytecode_address: Option<Address>,
    pub caller: Address,
    pub call_value: U256,
}

EVM contract information.

Fields

input: Bytes

Contracts data

bytecode: Bytecode

Bytecode contains contract code, size of original code, analysis with gas block and jump table. Note that current code is extended with push padding and STOP at end.

hash: Option<B256>

Bytecode hash for legacy. For EOF this would be None.

target_address: Address

Target address of the account. Storage of this address is going to be modified.

bytecode_address: Option<Address>

Address of the account the bytecode was loaded from. This can be different from target_address in the case of DELEGATECALL or CALLCODE

caller: Address

Caller of the EVM.

call_value: U256

Value send to contract from transaction or from CALL opcodes.

Implementations

impl Contract

pub fn new( input: Bytes, bytecode: Bytecode, hash: Option<B256>, target_address: Address, bytecode_address: Option<Address>, caller: Address, call_value: U256, ) -> Self

Instantiates a new contract by analyzing the given bytecode.

pub fn new_env<EvmWiringT: EvmWiring>( env: &EnvWiring<EvmWiringT>, bytecode: Bytecode, hash: Option<B256>, ) -> Self

Creates a new contract from the given [EnvWiring].

pub fn new_with_context( input: Bytes, bytecode: Bytecode, hash: Option<B256>, call_context: &CallInputs, ) -> Self

Creates a new contract from the given inputs.

pub fn is_valid_jump(&self, pos: usize) -> bool

Returns whether the given position is a valid jump destination.

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 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.
