Struct Code 

pub struct Code { /* private fields */ }

Finished machine code and the final offsets of its labels.

Examples

use isa_lang::x86_64::{Assembler, Inst, Mnemonic};

let mut asm = Assembler::new();
let entry = asm.label();
asm.bind(entry)?;
asm.emit(&Inst::new(Mnemonic::Ret, []))?;
let code = asm.finish()?;
assert_eq!(code.label_offset(entry), Some(0));
assert_eq!(code.into_bytes(), vec![0xC3]);

Implementations

impl Code

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

The machine code.

Examples

use isa_lang::x86_64::{Assembler, Inst, Mnemonic};

let mut asm = Assembler::new();
asm.emit(&Inst::new(Mnemonic::Cqo, []))?;
assert_eq!(asm.finish()?.bytes(), [0x48, 0x99]);

pub fn into_bytes(self) -> Vec<u8>

The machine code, by value.

Examples

use isa_lang::x86_64::Assembler;

assert!(Assembler::new().finish()?.into_bytes().is_empty());

pub fn label_offset(&self, label: Label) -> Option<usize>

Where label ended up, or None if it was never bound (or belongs to another assembler).

Examples

use isa_lang::x86_64::Assembler;

let mut asm = Assembler::new();
let unused = asm.label();
assert_eq!(asm.finish()?.label_offset(unused), None);

Trait Implementations

impl Eq for Code

impl PartialEq for Code

fn eq(&self, other: &Self) -> bool
