Struct EncryptedIndex 

pub struct EncryptedIndex { /* private fields */ }

Inverted index mapping ciphertext hash → Vec<record_id>.

Thread-safe via DashMap.

Implementations

impl EncryptedIndex

pub fn new( name: impl Into<String>, collection: impl Into<String>, field: impl Into<String>, ) -> Self

Create a new empty index.

Example

use amaters_core::storage::EncryptedIndex;

let index = EncryptedIndex::new("age_index", "users", "age");
// Insert a record: ciphertext bytes representing an encrypted age value
let ciphertext_bytes = b"fake_ciphertext_for_value_30";
index.insert(ciphertext_bytes, 42); // record_id = 42

// Look up candidates by the same ciphertext bytes
let candidates = index.lookup_candidates(ciphertext_bytes);
assert_eq!(candidates, vec![42]);

pub fn name(&self) -> &str

Name of this index.

pub fn collection(&self) -> &str

Collection this index belongs to.

pub fn field(&self) -> &str

Field this index covers.

pub fn insert(&self, ciphertext_bytes: &[u8], record_id: u64)

Insert a record into the index.

pub fn remove(&self, ciphertext_bytes: &[u8], record_id: u64)

Remove a specific record from the index.

pub fn lookup_candidates(&self, ciphertext_bytes: &[u8]) -> Vec<u64>

Look up candidate record IDs by ciphertext hash.

pub fn len(&self) -> usize

Number of distinct hash buckets currently in the index.

pub fn is_empty(&self) -> bool

Whether the index has no entries.

pub fn total_records(&self) -> usize

Total number of record IDs stored across all buckets.

pub fn serialize(&self) -> Result<Vec<u8>>

Serialize the index to bytes using oxicode.

pub fn deserialize(data: &[u8]) -> Result<Self>

Deserialize an index from bytes produced by serialize.

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
