Eof(Arc<Eof>)

Ethereum Object Format

Eip7702(Eip7702Bytecode)

EIP-7702 delegated bytecode

Implementations

impl Bytecode

pub fn new() -> Bytecode

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

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

Returns jump table if bytecode is analyzed.

pub fn hash_slow(&self) -> FixedBytes<32>

Calculates hash of the bytecode.

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

Returns 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) -> Bytecode

Creates a new legacy Bytecode.

pub fn new_raw(bytecode: Bytes) -> Bytecode

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) -> Bytecode

Creates a new EIP-7702 Bytecode from Address.

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

Creates a new raw Bytecode.

Returns an error on incorrect bytecode format.

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

Create new checked bytecode.

Panics

For possible panics see LegacyAnalyzedBytecode::new.

pub fn bytecode(&self) -> &Bytes

Returns a reference to the bytecode.

In case of EOF this will be the all code sections.

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

Pointer to the executable bytecode.

Note: EOF will return the pointer to the start of the code section. while legacy bytecode will point to the start of the bytes.

pub fn bytes(&self) -> Bytes

Returns bytes.

pub fn bytes_ref(&self) -> &Bytes

Returns raw bytes reference.

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

Returns raw bytes slice.

pub fn original_bytes(&self) -> Bytes

Returns 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<(), Error>

Formats the value using the given formatter.

impl Default for Bytecode

fn default() -> Bytecode

Returns the “default value” for a type.

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

fn deserialize<__D>( __deserializer: __D, ) -> Result<Bytecode, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for Bytecode

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

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: &Bytecode) -> 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: &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 PartialOrd for Bytecode

fn partial_cmp(&self, other: &Bytecode) -> 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 Serialize for Bytecode

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Bytecode

impl StructuralPartialEq for Bytecode

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.

Size: 64 bytes

Size for each variant:
