Struct bad64::Instruction

pub struct Instruction { /* fields omitted */ }

A decoded instruction

Implementations

impl Instruction

pub fn address(&self) -> u64

Returns the instruction address

Example

use bad64::decode;
// nop - "\x1f\x20\x03\xd5"
let decoded = decode(0xd503201f, 0x1000).unwrap();
assert_eq!(decoded.address(), 0x1000);

pub fn opcode(&self) -> u32

Returns the instruction opcode

Example

use bad64::decode;
// nop - "\x1f\x20\x03\xd5"
let decoded = decode(0xd503201f, 0x1000).unwrap();
assert_eq!(decoded.opcode(), 0xd503201f);

pub fn op(&self) -> Op

Returns the instruction operation

Example

use bad64::{decode, Op};
// nop - "\x1f\x20\x03\xd5"
let decoded = decode(0xd503201f, 0x1000).unwrap();
assert_eq!(decoded.op(), Op::NOP);

pub fn operands(&self) -> &[Operand]

Returns a slice of Operands

Example

use bad64::{decode, Operand, Reg};

// eor x0, x1, x2  - "\x20\x00\x02\xca"
let decoded = decode(0xca020020, 0x1000).unwrap();

let mut ops = decoded.operands();

assert_eq!(ops.len(), 3);
assert_eq!(ops[0], Operand::Reg { reg: Reg::X0, arrspec: None });
assert_eq!(ops[1], Operand::Reg { reg: Reg::X1, arrspec: None });
assert_eq!(ops[2], Operand::Reg { reg: Reg::X2, arrspec: None });

pub fn flags_set(&self) -> bool

Returns if the instruction updates the flags

Example

use bad64::decode;

// cmp x0, #0x41 - "\x1f\x04\x01\xf1"
let decoded = decode(0xf101041f, 0x1000).unwrap();
assert_eq!(decoded.flags_set(), true);

// nop - "\x1f\x20\x03\xd5"
let decoded = decode(0xd503201f, 0x1000).unwrap();
assert_eq!(decoded.flags_set(), false);

Trait Implementations

impl Clone for Instruction

fn clone(&self) -> Instruction

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Instruction

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for Instruction

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for Instruction

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher, 

Feeds a slice of this type into the given Hasher.

impl PartialEq<Instruction> for Instruction

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

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=.
