source · [−]

pub struct RawVacantEntryMut<'a, K: 'a, V: 'a, S: 'a> { /* private fields */ }

🔬 This is a nightly-only experimental API. (hash_raw_entry #56167)

Expand description

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.

    self,
    hash: u64,
    key: K,
    value: V
) -> (&'a mut K, &'a mut V) where
