# [−][src]Struct std::collections::hash_map::RawEntryBuilderMut

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

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

A builder for computing where in a HashMap a key-value pair would be stored.

See the `HashMap::raw_entry_mut` docs for usage examples.
