Struct borsh::maybestd::collections::hash_map::RawEntryBuilder

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

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

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

See the HashMap::raw_entry docs for usage examples.
