Struct EvmBasicBlock 

pub struct EvmBasicBlock {
    pub label: String,
    pub instructions: Vec<EvmInstruction>,
    pub is_jump_target: bool,
}

A basic block of EVM instructions with a named label.

Each block starts with a JUMPDEST if it is a jump target.

Fields

label: String

Symbolic label for this block (used in assembly output).

instructions: Vec<EvmInstruction>

The instructions in this block.

is_jump_target: bool

Whether this block needs a JUMPDEST at the start.

Implementations

impl EvmBasicBlock

pub fn new(label: impl Into<String>) -> Self

Create a new basic block with the given label.

pub fn new_jump_target(label: impl Into<String>) -> Self

Create a new basic block that is a jump target (has JUMPDEST).

pub fn push_instr(&mut self, instr: EvmInstruction)

Append an instruction to this block.

pub fn push_op(&mut self, opcode: EvmOpcode)

Append a simple opcode (no immediate data) to this block.

pub fn byte_len(&self) -> usize

Total byte count of all instructions in this block (excluding JUMPDEST).

pub fn encode(&self) -> Vec<u8>

Encode this block to raw bytes.
