Struct anymap2::raw::VacantEntry

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>

source

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.
