SegmentMeta

tantivy::index

Struct SegmentMeta 

Source 
pub struct SegmentMeta { /* private fields */ }
Expand description

SegmentMeta contains simple meta information about a segment.

For instance the number of docs it contains, how many are deleted, etc.

Implementations§

Source§

impl SegmentMeta

Source

pub fn id(&self) -> SegmentId

Returns the segment id.

Source

pub fn num_deleted_docs(&self) -> u32

Returns the number of deleted documents.

Source

pub fn list_files(&self) -> HashSet<PathBuf>

Returns the list of files that are required for the segment meta. Note: Some of the returned files may not exist depending on the state of the segment.

This is useful as the way tantivy removes files is by removing all files that have been created by tantivy and are not used by any segment anymore.

Source

pub fn relative_path(&self, component: SegmentComponent) -> PathBuf

Returns the relative path of a component of our segment.

It just joins the segment id with the extension associated with a segment component.

Source

pub fn max_doc(&self) -> u32

Return the highest doc id + 1

If there are no deletes, then num_docs = max_docs and all the doc ids contains in this segment are exactly (0..max_doc).

Source

pub fn num_docs(&self) -> u32

Return the number of documents in the segment.

Source

pub fn delete_opstamp(&self) -> Option<Opstamp>

Returns the Opstamp of the last delete operation taken in account in this segment.

Source

pub fn has_deletes(&self) -> bool

Returns true iff the segment meta contains delete information.

Source

pub fn with_max_doc(self, max_doc: u32) -> SegmentMeta

Updates the max_doc value from the SegmentMeta.
