Struct std_shims::collections::hash_map::RawEntryBuilder

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

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

Available on crate feature std only.

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

See the HashMap::raw_entry docs for usage examples.

Implementations

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
