Struct std::collections::hash_map::RawVacantEntryMut

pub struct RawVacantEntryMut<'a, K: 'a, V: 'a, S: 'a> { /* private fields */ }
🔬This is a nightly-only experimental API. (hash_raw_entry #56167)

A view into a vacant entry in a HashMap. It is part of the RawEntryMut enum.

Implementations

source 
impl<'a, K, V, S> RawVacantEntryMut<'a, K, V, S>
source 
pub fn insert(self, key: K, value: V) -> (&'a mut K, &'a mut V)
where
    K: Hash,
    S: BuildHasher,
🔬This is a nightly-only experimental API. (hash_raw_entry #56167)

Sets the value of the entry with the VacantEntry’s key, and returns a mutable reference to it.
