Macro kernel::init_static_sync

macro_rules! init_static_sync {
    ($($(#[$outer:meta])* $v:vis static $id:ident : $t:ty $(= $value:expr)?;)*) => { ... };
    (@call_new $t:ty, $value:expr) => { ... };
    (@call_new $t:ty,) => { ... };
}

Automatically initialises static instances of synchronisation primitives.

The syntax resembles that of regular static variables, except that the value assigned is that of the protected type (if one exists). In the examples below, all primitives except for CondVar require the inner value to be supplied.

Examples

struct Test {
    a: u32,
    b: u32,
}

init_static_sync! {
    static A: Mutex<Test> = Test { a: 10, b: 20 };

    /// Documentation for `B`.
    pub static B: Mutex<u32> = 0;

    pub(crate) static C: SpinLock<Test> = Test { a: 10, b: 20 };
    static D: CondVar;

    static E: RevocableMutex<Test> = Test { a: 30, b: 40 };
}
