Struct std::collections::hash_map::RawEntryBuilder

pub struct RawEntryBuilder<'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 docs for usage examples.

Methods

impl<'a, K, V, S> RawEntryBuilder<'a, K, V, S> where
    S: BuildHasher
[src]
