pub struct Guard<T: RefCnt, S: Strategy<T> = DefaultStrategy> { /* 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: RefCnt, S: Strategy<T>> Guard<T, S>
impl<T: RefCnt, S: Strategy<T>> Guard<T, S>
sourcepub fn into_inner(lease: Self) -> T
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.
sourcepub fn from_inner(inner: T) -> Self
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));
