Struct Decoded 

pub struct Decoded { /* private fields */ }

A decoded instruction: the Inst, how many bytes it took, and the form it matched.

Examples

use isa_lang::x86_64::decode;

let d = decode(&[0x48, 0x8B, 0x44, 0x24, 0x08, 0xC3])?;
assert_eq!(d.len(), 5);
assert_eq!(d.inst().to_string(), "mov rax, qword ptr [rsp+0x8]");
assert_eq!(d.form().syntax(), "MOV r64, r/m64");

Implementations

impl Decoded

pub const fn inst(&self) -> Inst

The instruction.

Examples

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

assert_eq!(decode(&[0xCC])?.inst(), Inst::new(Mnemonic::Int3, []));

pub const fn len(&self) -> usize

The number of bytes the instruction occupies (1 to 15).

Examples

use isa_lang::x86_64::decode;

assert_eq!(decode(&[0x0F, 0x1F, 0x44, 0x00, 0x00])?.len(), 5);

pub fn form(&self) -> &'static Form

The table row the bytes matched.

Examples

use isa_lang::x86_64::decode;

assert_eq!(decode(&[0x05, 1, 0, 0, 0])?.form().syntax(), "ADD EAX, imm32");

pub const fn flags(&self) -> FlagEffects

What the instruction does to the flags, with a condition code’s reads filled in.

Examples

use isa_lang::x86_64::{decode, Flags};

// sete al
assert_eq!(decode(&[0x0F, 0x94, 0xC0])?.flags().read(), Flags::ZF);
