Overview
mem_viewer is a Rust crate that provides a macro view_mem! to view the memory content of an arbitrary variable. It supports viewing memory content of different data types including integers, floating-point numbers, strings, pointers, vectors, boxed variables, and structs.
Usage
Add the following line to your Cargo.toml file:
[dependencies]
mem_viewer = "0.3.0"
Then, in your Rust code, you can use the view_mem! macro to view the memory content of a variable. Here's an example:
use mem_viewer::*;
let my_str: &str = "π¦Helloπ";
view_mem!(*my_str);
This will print the memory content of my_var to the console.
Example Output
Name: *my_str
Type: str
Addr: 00007ff7f23fa4b8
Size: 13 bytes
Aloc: Likely Stack

Safe Usage
For safe mode, you can use the safe_view_mem! macro to view the memory content of a variable. Here's an example:
use mem_viewer::*;
let my_str: &str = "π¦Helloπ";
view_mem!(my_str);
Example Safe Output
Name : my_str
Type : &str
Addr : 00007ff7f23fa4b8
