Struct Assembler 

pub struct Assembler { /* private fields */ }

Two-pass assembler for EVM bytecode.

Implementations

impl Assembler

pub fn new() -> Assembler

Creates a new assembler.

pub fn with_config(config: AssemblerConfig) -> Assembler

Creates a new assembler with the given configuration.

pub fn clear(&mut self)

Clears all emitted instructions and local identifiers while retaining allocated storage.

pub fn new_label(&mut self) -> Label

Creates a new label.

pub fn new_deferred_const(&mut self) -> DeferredConst

Creates a new deferred constant.

pub fn emit_op(&mut self, opcode: u8)

Emits a raw opcode.

pub fn emit_push(&mut self, value: Uint<256, 4>)

Emits a push instruction with an immediate value.

pub fn emit_push_label(&mut self, label: Label)

Emits a push instruction that will be resolved to a label’s offset.

pub fn emit_push_deferred(&mut self, id: DeferredConst)

Emits a push instruction for a deferred constant.

pub fn set_deferred_const(&mut self, id: DeferredConst, value: Uint<256, 4>)

Sets the value of a deferred constant.

pub fn emit_push_immutable(&mut self, id: u32)

Emits a PUSH32 zero placeholder for the immutable identified by id.

pub fn define_label(&mut self, label: Label)

Defines a label and emits a JUMPDEST at the current position.

pub fn assemble(&mut self) -> AssembledCode

Assembles the instructions into bytecode. Uses an iterative two-pass algorithm that handles PUSH width changes.

Trait Implementations

impl Debug for Assembler

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

Formats the value using the given formatter.

impl Default for Assembler

fn default() -> Assembler

Returns the “default value” for a type.
