Magical Data Sharing for Rust
## Usage
```rs
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::(0).unwrap();
// take ownership of data
let data = magical::take_at::(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.
