spinning_top

基于lock_api提供的抽象的简单自旋锁crate。

示例

首先，将crate作为依赖项导入到你的Cargo.toml中。然后你可以按以下方式使用它

use spinning_top::Spinlock;

fn main() {
    // Wrap some data in a spinlock
    let data = String::from("Hello");
    let spinlock = Spinlock::new(data);
    make_uppercase(&spinlock); // only pass a shared reference
    // We have ownership of the spinlock, so we can extract the data without locking
    // Note: this consumes the spinlock
    let data = spinlock.into_inner();
    assert_eq!(data.as_str(), "HELLO");
}

fn make_uppercase(spinlock: &Spinlock<String>) {
    // Lock the spinlock to get a mutable reference to the data
    let mut locked_data = spinlock.lock();
    assert_eq!(locked_data.as_str(), "Hello");
    locked_data.make_ascii_uppercase();

    // the lock is automatically freed at the end of the scope
}

Spinlock::new是一个const函数。这使得Spinlock类型可以在静态中使用

use spinning_top::Spinlock;

static DATA: Spinlock<u32> = Spinlock::new(0);

fn main() {
    let mut data = DATA.lock();
    *data += 1;
    assert_eq!(*data, 1);
}
