Enum tantivy::SegmentComponent

pub enum SegmentComponent {
    Postings,
    Positions,
    FastFields,
    FieldNorms,
    Terms,
    Store,
    TempStore,
    Delete,
}

Enum describing each component of a tantivy segment. Each component is stored in its own file, using the pattern segment_uuid.component_extension, except the delete component that takes an segment_uuid.delete_opstamp.component_extension

Variants

Postings

Postings (or inverted list). Sorted lists of document ids, associated to terms

Positions

Positions of terms in each document.

FastFields

Column-oriented random-access storage of fields.

FieldNorms

Stores the sum of the length (in terms) of each field for each document. Field norms are stored as a special u64 fast field.

Terms

Dictionary associating Terms to TermInfos which is simply an address into the postings file and the positions file.

Store

Row-oriented, compressed storage of the documents. Accessing a document from the store is relatively slow, as it requires to decompress the entire block it belongs to.

TempStore

Temporary storage of the documents, before streamed to Store.

Delete

Bitset describing which document of the segment is deleted.

Implementations

impl SegmentComponent

pub fn iterator() -> Iter<'static, SegmentComponent>

Iterates through the components.

Trait Implementations

impl Clone for SegmentComponent

fn clone(&self) -> SegmentComponent

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl PartialEq<SegmentComponent> for SegmentComponent

fn eq(&self, other: &SegmentComponent) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=.
