Struct RefreshableGuard

Source
pub struct RefreshableGuard<T, S = HybridStrategy<DefaultConfig>>
where T: RefCnt, S: Strategy<T>,
{ /* private fields */ }
Expand description

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§

Source§

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

Source

pub fn into_inner(lease: Guard<T, S>) -> T

Available on crate feature redis only.

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.

Source

pub fn from_inner(inner: T) -> Guard<T, S>

Available on crate feature redis only.

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));
