Enum IndexType 

pub enum IndexType {
    Ore,
    Match {
        tokenizer: Tokenizer,
        token_filters: Vec<TokenFilter>,
        k: usize,
        m: usize,
        include_original: bool,
    },
    Unique {
        token_filters: Vec<TokenFilter>,
    },
    SteVec {
        prefix: String,
        term_filters: Vec<TokenFilter>,
    },
}

Variants

Ore

Match

Fields

tokenizer: Tokenizer

token_filters: Vec<TokenFilter>

k: usize

m: usize

include_original: bool

Indicates if the original term should be added as a term which allows a match index to be used for equality

Unique

This is called Unique because a Hash index must always have a unique constraint on it but it is technically a Determinstic index. Naming is hard.

Fields

token_filters: Vec<TokenFilter>

SteVec

Fields

prefix: String

term_filters: Vec<TokenFilter>

Implementations

impl IndexType

pub fn supports(&self, op: &Operator, cast_type: &ColumnType) -> bool

Returns true or false based on the below:

Non string type indexes support:

Ore: Eq | Lt | Lte | Gt | Gte, Unique: Eq

String type indexes support:

Match: Like | ILike Ore: Lt | Lte | Gt | Gte, Unique: Eq

pub fn supported_operations(&self, cast_type: &ColumnType) -> Vec<Operator>

pub fn is_orderable(&self) -> bool

pub fn as_str(&self) -> &str

String identifier for the index type. Useful when naming columns

Trait Implementations

impl Clone for IndexType

fn clone(&self) -> IndexType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IndexType

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for IndexType

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for IndexType

fn eq(&self, other: &IndexType) -> 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 IndexType

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
