Enum IndexKind 

pub enum IndexKind {
    Bitmap,
    Fm,
    Ann,
    Sparse,
    MinHash,
}

The kind of secondary index the Kit declares on a column.

Variants

Bitmap

Equality / IN acceleration (the default).

Fm

FM-index substring search (contains(col, needle) pushes to FmContains).

Ann

HNSW approximate-nearest-neighbour index for Embedding columns.

Sparse

SPLADE-style learned-sparse retrieval index for Sparse columns.

MinHash

MinHash/LSH set-similarity index over a JSON-array set column (accelerates set_similarity).

Trait Implementations

impl Clone for IndexKind

fn clone(&self) -> IndexKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for IndexKind

impl Debug for IndexKind

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for IndexKind

fn default() -> IndexKind

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for IndexKind

fn deserialize<__D>( __deserializer: __D, ) -> Result<IndexKind, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for IndexKind

impl PartialEq for IndexKind

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for IndexKind

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
