memprint()

memprint provides a single MemPrint trait (including a derive macro for it!),
which allows you to print the underlying memory layout of a type.

Example

example output

here are the two ways ye can use your newfound powers:

use memprint::MemPrint;

#[derive(MemPrint)]
struct MyStruct {
    c: u8,
    a: i32,
    b: f32,
}

impl MyStruct {
    fn new(a: i32, b: f32, c: u8) -> Self {
        Self { a, b, c }
    }
}

fn main() {
    let struc = MyStruct::new(42, 3.14, b'A');
    
    // provides a detailed printout of a single struct
    MyStruct::memprint(&struc);

    let mut vec = Vec::new();

    vec.push(MyStruct::new(42,    3.14, b'A'));
    vec.push(MyStruct::new(69,    2.71, b'B'));
    vec.push(MyStruct::new(1337,  1.41, b'C'));
    vec.push(MyStruct::new(9001,  0.0,  b'D'));
    vec.push(MyStruct::new(80085, -1.0, b'E'));
    println!("\n\n");

    // prints a colour coded block of memory, representing the elements of the slice
    MyStruct::memprint_block(&vec);
}

todos

  • add support for enums and unions
  • use the colour coded printout if any fields on a struct are also structs with the MemPrint trait
