Enum BloomFilterQuery 

pub enum BloomFilterQuery {
    Equals(ScalarValue),
    IsNull(),
    IsIn(Vec<ScalarValue>),
}

A query that a BloomFilter index can satisfy

This is a subset of SargableQuery that only includes operations that bloom filters can efficiently handle: equals, is_null, and is_in queries.

Variants

Equals(ScalarValue)

Retrieve all row ids where the value is exactly the given value

IsNull()

Retrieve all row ids where the value is null

IsIn(Vec<ScalarValue>)

Retrieve all row ids where the value is in the given set of values

Trait Implementations

impl AnyQuery for BloomFilterQuery

fn as_any(&self) -> &dyn Any

Cast the query as Any to allow for downcasting

fn format(&self, col: &str) -> String

Format the query as a string for display purposes

fn to_expr(&self, col: String) -> Expr

Convert the query to a datafusion expression

fn dyn_eq(&self, other: &dyn AnyQuery) -> bool

Compare this query to another query

impl Clone for BloomFilterQuery

fn clone(&self) -> BloomFilterQuery

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BloomFilterQuery

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

Formats the value using the given formatter.

impl PartialEq for BloomFilterQuery

fn eq(&self, other: &BloomFilterQuery) -> 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.
