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)

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

source

pub fn insert_hashed_nocheck( self, hash: u64, 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)

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