Struct Guard

pub struct Guard<T: RefCnt, S: Strategy<T> = DefaultStrategy> { /* private fields */ }

A temporary storage of the pointer.

This guard object is returned from most loading methods (with the notable exception of load_full). It dereferences to the smart pointer loaded, so most operations are to be done using that.

Implementations

impl<T: RefCnt, S: Strategy<T>> Guard<T, S>

pub fn into_inner(lease: Self) -> T

Converts it into the held value.

This, on occasion, may be a tiny bit faster than cloning the Arc or whatever is being held inside.

pub fn from_inner(inner: T) -> Self

Create a guard for a given value inner.

This can be useful on occasion to pass a specific object to code that expects or wants to store a Guard.

Example

// Create two guards pointing to the same object
let g1 = p.load();
let g2 = Guard::<_, DefaultStrategy>::from_inner(Arc::clone(&*g1));
