Memory layout analysis tool for rust structs, enums, unions, tuples, and references, prints to console using ansi escape codes.

Simply derive Dissectible and call print_dissection_info to get a well formatted overview.

use struct_scalpel::{Dissectible, print_dissection_info};

#[derive(Dissectible)]
struct Person {
    name: String,
    age: u32,
    is_student: bool,
    height: f64,
    favorite_numbers: Vec<u8>,
}

fn main() {
    print_dissection_info::<Person>();
}

With dissect_std you can even disect some std items, with only a few type path deviations for private types.

• String
• Option
• Result<T, E>
• Box<T, A: Allocator>
• Rc
• cell
  • UnsafeCell
  • Cell
  • RefCell
  • OnceCell
• sync
  • OnceLock

Disclaimer: This may not work in all cases, such as where some fields are unsized or dependant on a sys (os) implementation

This also works with generics and different layout strategies
