Struct IndexInfo 

pub struct IndexInfo {
    pub format_version: u32,
    pub levels: u32,
    pub metric: Metric,
    pub is_normalized: Option<bool>,
    pub total_items: u32,
    pub next_item_id: u32,
    pub total_representatives: u32,
}

An index’s info/* fields and representative count, read without loading the tree.

Fields

format_version: u32

The version of the on-disk format. An index missing the field but otherwise complete reads as the current version.

levels: u32

Node levels below the root; the last one holds the leaves.

metric: Metric

is_normalized: Option<bool>

Whether every stored embedding is unit-length, or None if the index does not say.

total_items: u32

Items stored in the index.

next_item_id: u32

The id insert gives the next item. Equal to total_items unless a crash stopped an insert between taking ids and writing the items.

total_representatives: u32

How many representatives the build picked, one per leaf node. Read from /rep_item_ids’s length.

Implementations

impl IndexInfo

pub fn load(index_path: PathBuf) -> Result<Self>

Loads an index’s info fields from index_path.
