Enum IndexType 

pub enum IndexType {
    BTree,
    Hash,
    GIN,
    GiST,
    SPGiST,
    BRIN,
    Bloom,
    Custom(Ident),
}

Indexing method used by that index.

This structure isn’t present on ANSI, but is found at least in MySQL CREATE TABLE, MySQL CREATE INDEX, and Postgresql CREATE INDEX statements.

Variants

BTree

B-Tree index (commonly default for many databases).

Hash

Hash index.

GIN

Generalized Inverted Index (GIN).

GiST

Generalized Search Tree (GiST) index.

SPGiST

Space-partitioned GiST (SPGiST) index.

BRIN

Block Range Index (BRIN).

Bloom

Bloom filter based index.

Custom(Ident)

Users may define their own index types, which would not be covered by the above variants.

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 Display for IndexType

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

Formats the value using the given formatter.

impl Hash for IndexType

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for IndexType

fn cmp(&self, other: &IndexType) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

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 PartialOrd for IndexType

fn partial_cmp(&self, other: &IndexType) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Visit for IndexType

fn visit<V: Visitor>(&self, visitor: &mut V) -> ControlFlow<V::Break>

Visit this node with the provided Visitor.

impl VisitMut for IndexType

fn visit<V: VisitorMut>(&mut self, visitor: &mut V) -> ControlFlow<V::Break>

Mutably visit this node with the provided VisitorMut.

impl Eq for IndexType

impl StructuralPartialEq for IndexType
