Enum Bytecode

pub enum Bytecode {
    LegacyRaw(Bytes),

    Eof(Arc<Eof>),
    Eip7702(Eip7702Bytecode),
}

State of the Bytecode analysis.

Variants

LegacyRaw(Bytes)

No analysis has been performed.

LegacyAnalyzed(LegacyAnalyzedBytecode)

The bytecode has been analyzed for valid jump destinations.

Eof(Arc<Eof>)

Ethereum Object Format

Eip7702(Eip7702Bytecode)

EIP-7702 delegated bytecode

Implementations

impl Bytecode

pub fn new() -> Self

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

Return jump table if bytecode is analyzed

pub fn hash_slow(&self) -> B256

Calculate hash of the bytecode.

pub const fn eof(&self) -> Option<&Arc<Eof>>

Return reference to the EOF if bytecode is EOF.

pub const fn is_eof(&self) -> bool

Returns true if bytecode is EOF.

pub const fn is_eip7702(&self) -> bool

Returns true if bytecode is EIP-7702.

pub fn new_legacy(raw: Bytes) -> Self

Creates a new legacy Bytecode.

pub fn new_raw(bytecode: Bytes) -> Self

Creates a new raw Bytecode.

Panics

Panics if bytecode is in incorrect format.

pub fn new_eip7702(address: Address) -> Self

Creates a new EIP-7702 Bytecode from Address.

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

Creates a new raw Bytecode.

Returns an error on incorrect Bytecode format.

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

Create new checked bytecode.

Safety

Bytecode needs to end with STOP (0x00) opcode as checked bytecode assumes that it is safe to iterate over bytecode without checking lengths.

pub fn bytecode(&self) -> &Bytes

Returns a reference to the bytecode.

In case of EOF this will be the first code section.

pub fn is_execution_ready(&self) -> bool

Returns false if bytecode can’t be executed in Interpreter.

pub fn bytes(&self) -> Bytes

Returns bytes

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

Returns bytes slice

pub fn original_bytes(&self) -> Bytes

Returns a reference to the original bytecode.

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

Returns the original bytecode as a byte slice.

pub fn len(&self) -> usize

Returns the length of the original bytes.

pub fn is_empty(&self) -> bool

Returns whether the bytecode is empty.

Trait Implementations

impl Clone for Bytecode

fn clone(&self) -> Bytecode

Returns a copy 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: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

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 PartialEq for Bytecode

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Bytecode

impl StructuralPartialEq for Bytecode
