Enum IndexType 

pub enum IndexType {
    Hash,
    Sorted,
    Array,
    Unique,
}

Type of secondary index on a collection field.

Variants

Hash

Hash-based equality index for fast point lookups.

Sorted

B-tree sorted index for range queries on numeric fields.

Array

Hash-based index for array element membership queries.

Unique

Hash-based unique constraint index.

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 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 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.
