Struct HashIndex 

pub struct HashIndex<K: Hash + Eq + Clone> { /* private fields */ }

A hash index mapping a key to a row offset in a table. L1 cache layer — fast in-memory lookups.

Implementations

impl<K: Hash + Eq + Clone> HashIndex<K>

pub fn new() -> Self

pub fn insert(&mut self, key: K, row_offset: u64)

pub fn lookup(&self, key: &K) -> Option<u64>

pub fn delete(&mut self, key: &K)

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn clear(&mut self)

Remove all entries.

pub fn iter(&self) -> impl Iterator<Item = (&K, &u64)>

Iterate over all (key, offset) entries.
