Crate lde [−] [src]

Length Disassembler Engine

Supports x86 and x86_64 up to SSE4.2.

Valid opcodes will be length disassembled correctly. Invalid opcodes may be rejected on a best-effort basis.

Examples

Get the length of the first opcode in a byte slice.

use lde::{InsnSet, x64};

assert_eq!(x64::ld(b"\x40\x55\x48\x83\xEC\xFC\x00\x80"), 2);

Iterate over the opcodes contained in a byte slice, returning the opcode and its virtual address.

use lde::{InsnSet, x64};

let mut it = x64::lde(b"\x40\x55\x48\x83\xEC*\x00\x80", 0x1000);
assert_eq!(it.next(), Some(x64::code(b"\x40\x55", 0x1000)));
assert_eq!(it.next(), Some(x64::code(b"\x48\x83\xEC*", 0x1002)));
assert_eq!(it.next(), None);

Custom Display and Debug formatting including pretty printing support with #.

use lde::{InsnSet, x64};

let it = x64::lde(b"\x40\x55\x48\x83\xEC*\x00\x80", 0);
assert_eq!(format!("{:?}", it), "[4055] [4883EC2A] 0080");
assert_eq!(format!("{:#?}", it), "[40 55] [48 83 EC 2A] 00 80");
assert_eq!(format!("{:}", it), "4055\n4883EC2A\n");
assert_eq!(format!("{:#}", it), "40 55\n48 83 EC 2A\n");
