Struct IndexSnapshot 

pub struct IndexSnapshot {
    pub entries: HashMap<u64, VectorEntry>,
    pub seq: u64,
}

An immutable snapshot of the current index state.

Internally stored as a map from vector ID to VectorEntry for O(1) lookups.

Fields

entries: HashMap<u64, VectorEntry>

All entries in this snapshot, keyed by vector ID

seq: u64

Sequence number associated with this snapshot

Implementations

impl IndexSnapshot

pub fn new() -> Self

Create an empty snapshot at sequence 0.

pub fn from_entries(entries: Vec<VectorEntry>, seq: u64) -> Self

Create a snapshot with the given entries and sequence number.

pub fn upsert(&mut self, entry: VectorEntry)

Insert or update an entry.

pub fn remove(&mut self, id: u64) -> bool

Remove an entry by ID. Returns true if the entry was present.

pub fn get(&self, id: u64) -> Option<&VectorEntry>

Return the entry for the given ID, if present.

pub fn len(&self) -> usize

Number of entries in the snapshot.

pub fn is_empty(&self) -> bool

Returns true if the snapshot contains no entries.
