Struct boolean_enums::lstd::collections::hash_map::RawOccupiedEntryMut

pub struct RawOccupiedEntryMut<'a, K, V> where
    K: 'a + 'a,
    V: 'a + 'a,  { /* fields omitted */ }

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

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