Struct lifelink::Guard

source · 
pub struct Guard<'a, C: Ctor> { /* private fields */ }
Expand description

A guard value that provides temporary access to the wrapped value. Care must be taken to ensure that this value is dropped properly. Leaking the guard value may lead to a deadlock.

Guard<'_, C> implements Send and Sync when the wrapped values produced by C are Sync.
