magical-global

Tip

It is a shortcut when sharing variables like C code with ease, and is not a good technique from the Rust perspective.

Magical Data Sharing for Rust

Usage

use magical_global as magical;

fn main() {
  let data:usize = 0;
  // Set data to magical global
  if magical::set_at(Box::new(data), 0).is_err() {
      println!("failed to set data");
      return;
  };
  // read global
  let shared_data = magical::get_mut_at::<usize>(0).unwrap();
  // take ownership of data
  let data = magical::take_at::<usize>(0).unwrap();
}

Read the example code to learn more.

Limitations

• The possible areas where data can be placed are from 0 to 31.
• This crate has no memory management features.
  • Recommend using the take_at function to free memory with the rust function.

Examples

Example code can be executed with cargo run --example sharing or cargo run --example locking

sharing is a simple data share, and locking is an Example of Mutex Lock code.
