Methods
impl<'a, A: ?Sized + UncheckedAnyExt> Entry<'a, A>
[src]
unsafe fn or_insert(self, default: Box<A>) -> &'a mut A
Ensures a value is in the entry by inserting the default if empty, and returns a mutable reference to the value in the entry.
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.
unsafe fn or_insert_with<F: FnOnce() -> Box<A>>(self, default: F) -> &'a mut A
Ensures a value is in the entry by inserting the result of the default function if empty, and returns a mutable reference to the value in the entry.
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.
