Struct IndexMeta 

pub struct IndexMeta {
    pub version: u32,
    pub segments: Vec<SegmentMeta>,
}

The index’s manifest: which segments are active, and what is deleted.

Fields

version: u32

segments: Vec<SegmentMeta>

Implementations

impl IndexMeta

pub fn read(base: &Path) -> Result<Self, String>

Read meta.json, or the default when there is none (an index that has never been committed, or one from before segments).

pub fn write(&self, base: &Path) -> Result<(), String>

Write meta.json atomically: a crash leaves the previous manifest, so the segments it names are still the index.

pub fn live_vectors(&self) -> usize

Vectors the segments still answer for.

pub fn files(&self) -> Vec<String>

The files these segments own, for a store that syncs by name.
