Function hash_key

src/map.rs:43–50

Computes a 64-bit hash of a key using the xxHash algorithm. This hash function is used to: 1. Determine which shard a key-value pair belongs to (via modulo) 2. Enable fast lookups by storing the hash alongside the data # Arguments `key` - The key to hash # Returns A 64-bit hash value

(key: &K)

/// # Returns
/// A 64-bit hash value
pub(crate) fn hash_key<K>(key: &K) -> u64
where
    K: Hash,
{
    let mut hasher = XxHash64::with_seed(0);
    key.hash(&mut hasher);
    hasher.finish()
}

/// Serialization job for a single `HashMap` shard.
