Struct BytecodeProgram 

pub struct BytecodeProgram {
    pub instructions: Vec<Instruction>,
}

A compiled, flat sequence of Instructions.

Fields

instructions: Vec<Instruction>

The ordered list of instructions.

Implementations

impl BytecodeProgram

pub fn new() -> Self

Create an empty program.

pub fn push(&mut self, instr: Instruction) -> usize

Append an instruction and return its absolute index.

pub fn patch_jump(&mut self, idx: usize, target: usize)

Patch the jump target of the instruction at idx.

Panics in debug builds if idx does not contain a jump instruction.

pub fn len(&self) -> usize

Return the number of instructions in the program.

pub fn is_empty(&self) -> bool

Return true if the program contains no instructions.
