Struct juicebox_asm::prelude::Label

pub struct Label { /* private fields */ }

A label which is used as target for jump instructions.

use juicebox_asm::prelude::*;

let mut lbl = Label::new();
let mut asm = Asm::new();

// Skip the mov instruction.
asm.jmp(&mut lbl);
asm.mov(Reg64::rax, Reg64::rax);
asm.bind(&mut lbl);

Panics

Panics if the label is dropped while not yet bound, or having unresolved relocations. This is mainly a safety-guard to detect wrong usage.

Implementations

impl Label

pub fn new() -> Label

Create a new unbound Label.

Trait Implementations

impl Drop for Label

fn drop(&mut self)

Executes the destructor for this type.

impl Jmp<&mut Label> for Asm

fn jmp(&mut self, op1: &mut Label)

Emit an unconditional jump instruction.

impl Jnz<&mut Label> for Asm

fn jnz(&mut self, op1: &mut Label)

Emit a conditional jump if not zero instruction (ZF = 0).

impl Jz<&mut Label> for Asm

fn jz(&mut self, op1: &mut Label)

Emit a conditional jump if zero instruction (ZF = 1).
