Macro rumtk_critical_section_write 

macro_rules! rumtk_critical_section_write {
    ( $lock:expr, $function:expr ) => { ... };
}

Using a standard spin lock SafeLock, lock it and execute the critical section. The critical section itself is a synchronous function or closure. In this case, the critical section attempts to modify the internal state of a guarded dataset.

Example

use rumtk_core::{rumtk_new_lock, rumtk_critical_section_write};

let data = 5;
let new_data = 10;
let lock = rumtk_new_lock!(data);
let result = rumtk_critical_section_write!(
    lock,
    |mut guard| {
        *guard = new_data;
    }
);

assert_eq!(result, (), "Critical section yielded invalid result!");
