source · pub struct VacantEntry<'a, A: ?Sized + UncheckedAnyExt> { /* private fields */ }
Expand description
A view into a single empty location in a RawMap
.
Implementations§
source§impl<'a, A: ?Sized + UncheckedAnyExt> VacantEntry<'a, A>
impl<'a, A: ?Sized + UncheckedAnyExt> VacantEntry<'a, A>
sourcepub unsafe fn insert(self, value: Box<A>) -> &'a mut A
pub unsafe fn insert(self, value: Box<A>) -> &'a mut A
Sets the value of the entry with the VacantEntry’s key, and returns a mutable reference to it
§Safety
It is the caller’s responsibility to ensure that the key of the entry
corresponds with the type ID of value
. If they do not, memory
safety may be violated.
