Struct SipHasher13

#[doc(hidden)] pub struct SipHasher13 {
    hasher: Hasher<Sip13Rounds>,
}

👎Deprecated since 1.13.0: use std::hash::DefaultHasher instead

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

An implementation of SipHash 1-3.

This is currently the default hashing function used by standard library (e.g., collections::HashMap uses it by default).
