Struct Meta 

pub struct Meta {
    pub schema_version: u32,
    pub segments: Vec<u64>,
    pub next_segment_id: u64,
    pub last_indexed: u64,
    pub doc_count: u64,
    pub symbol_count: u64,
    pub indexed_git_head: String,
    pub indexed_branch: String,
    pub pending_tombstones: Vec<PendingTombstones>,
}

Index-wide manifest describing the set of live segments.

Fields

schema_version: u32

segments: Vec<u64>

IDs of segments that make up the current index.

next_segment_id: u64

Monotonic counter for allocating new segment IDs.

last_indexed: u64

Unix timestamp (seconds) of the last successful index operation.

doc_count: u64

Total live documents across all segments.

symbol_count: u64

Total symbols across all segments.

indexed_git_head: String

Git commit sha at the time of indexing (empty if not a repo). Lets callers detect that the working tree moved (e.g. a branch switch).

indexed_branch: String

Git branch name at the time of indexing (empty if not a repo).

pending_tombstones: Vec<PendingTombstones>

Deletes published with the manifest but not yet applied to live bitmaps (see PendingTombstones). Normally empty; non-empty only in the window between an incremental publish and its bitmap writes (or after a crash inside that window, until the next index op recovers).

Implementations

impl Meta

pub fn load(path: &Path) -> Result<Meta>

pub fn save(&self, path: &Path) -> Result<()>

pub fn record_git_head(&mut self, root: &Path)

Record the current git HEAD/branch for the indexed tree (best-effort).

pub fn touch_now(&mut self)

pub fn alloc_segment(&mut self) -> u64
