Struct Bytecode 

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

Ethereum EVM bytecode.

Implementations

impl Bytecode

pub fn new() -> Self

Creates a new legacy analyzed Bytecode with exactly one STOP opcode.

pub fn new_legacy(raw: Bytes) -> Self

Creates a new legacy Bytecode by analyzing raw bytes.

pub fn new_raw(bytecode: Bytes) -> Self

Creates a new raw Bytecode.

Panics

Panics if bytecode is in incorrect format. If you want to handle errors use Self::new_raw_checked.

pub fn new_eip7702(address: Address) -> Self

Creates a new EIP-7702 Bytecode from Address.

pub fn new_raw_checked(bytes: Bytes) -> Result<Self, BytecodeDecodeError>

Creates a new raw Bytecode.

Returns an error on incorrect bytecode format.

pub fn new_eip7702_raw(bytes: Bytes) -> Result<Self, Eip7702DecodeError>

Creates a new EIP-7702 Bytecode from raw bytes.

Returns an error if the bytes are not valid EIP-7702 bytecode.

pub fn new_analyzed( bytecode: Bytes, original_len: usize, jump_table: JumpTable, ) -> Self

Create new checked bytecode from pre-analyzed components.

Panics

• If original_len is greater than bytecode.len()
• If jump table length is less than original_len
• If bytecode is empty

pub fn kind(&self) -> BytecodeKind

Returns the kind of bytecode.

pub fn is_legacy(&self) -> bool

Returns true if bytecode is legacy.

pub fn is_eip7702(&self) -> bool

Returns true if bytecode is EIP-7702.

pub fn eip7702_address(&self) -> Option<Address>

Returns the EIP-7702 delegated address if this is EIP-7702 bytecode.

pub fn legacy_jump_table(&self) -> Option<&JumpTable>

Returns jump table if bytecode is legacy analyzed.

pub fn hash_slow(&self) -> B256

Calculates or returns cached hash of the bytecode.

pub fn bytecode(&self) -> &Bytes

Returns a reference to the bytecode bytes.

For legacy bytecode, this includes padding. For EIP-7702, this is the raw bytes.

pub fn bytecode_ptr(&self) -> *const u8

Pointer to the bytecode bytes.

pub fn bytes(&self) -> Bytes

Returns a clone of the bytecode bytes.

pub fn bytes_ref(&self) -> &Bytes

Returns a reference to the bytecode bytes.

pub fn bytes_slice(&self) -> &[u8]

Returns the bytecode as a slice.

pub fn original_bytes(&self) -> Bytes

Returns the original bytecode without padding.

pub fn original_byte_slice(&self) -> &[u8]

Returns the original bytecode as a byte slice without padding.

pub fn len(&self) -> usize

Returns the length of the original bytes (without padding).

pub fn is_empty(&self) -> bool

Returns whether the bytecode is empty.

pub fn iter_opcodes(&self) -> BytecodeIterator<'_>

Returns an iterator over the opcodes in this bytecode, skipping immediates.

Trait Implementations

impl Clone for Bytecode

fn clone(&self) -> Bytecode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Bytecode

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

Formats the value using the given formatter.

impl Default for Bytecode

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Bytecode

fn deserialize<D: Deserializer<'de>>(deserializer: D) -> Result<Self, D::Error>

Deserialize this value from the given Serde deserializer.

impl Hash for Bytecode

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 Ord for Bytecode

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Bytecode

fn eq(&self, other: &Self) -> 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 PartialOrd for Bytecode

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Sealable for Bytecode

fn hash_slow(&self) -> B256
