Implementations

impl Code

pub fn from_bytecode_unchecked(code: Bytes, hash: H256) -> Self

pub fn from_bytecode(code: Bytes, crypto: &dyn Crypto) -> Self

code is the logical, unpadded bytecode; BYTECODE_PADDING STOP bytes are appended internally by from_parts_unchecked.

pub fn from_parts_unchecked( hash: H256, code: &[u8], jump_targets: Arc<[u32]>, ) -> Self

Builds a Code from precomputed parts. The caller must guarantee hash and jump_targets correspond to code; neither is recomputed or validated.

code is the logical, unpadded bytecode: this function appends BYTECODE_PADDING STOP bytes and records the original length in bytecode_len. Never pass a pre-padded buffer, or the logical length and every JUMPDEST/PUSH offset derived from it would be wrong.

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

pub fn code_bytes(&self) -> Bytes

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

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

Returns the padded bytecode buffer (real code + BYTECODE_PADDING trailing STOPs) used by the opcode dispatch loop to read opcodes without bounds checks. Use Code::code for the real, unpadded bytecode.

pub fn size(&self) -> usize

Estimates the size of the Code struct in bytes (including stack size and heap allocation).

Note: This is an estimation and may not be exact.

Returns

usize - Estimated size in bytes

Trait Implementations

impl Clone for Code

fn clone(&self) -> Code

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Code

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

Formats the value using the given formatter.

impl Default for Code

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Code

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

Deserialize this value from the given Serde deserializer.

impl Eq for Code

impl Hash for Code

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 Code

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

fn serialize<S: Serializer>(&self, serializer: S) -> Result<S::Ok, S::Error>

Serialize this value into the given Serde serializer.
