Struct Contract

pub struct Contract {
    pub input: Bytes,
    pub bytecode: Bytecode,
    pub hash: Option<FixedBytes<32>>,
    pub target_address: Address,
    pub bytecode_address: Option<Address>,
    pub caller: Address,
    pub call_value: Uint<256, 4>,
}

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<FixedBytes<32>>

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: Uint<256, 4>

Value send to contract from transaction or from CALL opcodes.

Implementations

impl Contract

pub fn new( input: Bytes, bytecode: Bytecode, hash: Option<FixedBytes<32>>, target_address: Address, bytecode_address: Option<Address>, caller: Address, call_value: Uint<256, 4>, ) -> Contract

Instantiates a new contract by analyzing the given bytecode.

pub fn new_env( env: &Env, bytecode: Bytecode, hash: Option<FixedBytes<32>>, ) -> Contract

Creates a new contract from the given Env.

pub fn new_with_context( input: Bytes, bytecode: Bytecode, hash: Option<FixedBytes<32>>, call_context: &CallInputs, ) -> Contract

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<(), Error>

Formats the value using the given formatter.

impl Default for Contract

fn default() -> Contract

Returns the “default value” for a type.
