Automatically restores the original function after execution.

Example

use windjammer_runtime::mock_function::with_mock;

fn get_time() -> i64 { 0 } // Simplified

with_mock("get_time", || 12345i64, || {
    // Mock is active here
    // let time = get_time();
    // assert_eq!(time, 12345);
});
// Mock is automatically cleared
