Enum ColumnModifier 

#[repr(u8)]
pub enum ColumnModifier {
    TimeKey = 0,
    SpatialIndex = 1,
}

Column-level modifiers that designate special engine roles.

These tell the engine which column serves a specialized purpose. Extensible for future column roles (e.g., PartitionKey, SortKey).

Variants

TimeKey = 0

This column is the time-partitioning key (timeseries profile). Exactly one required for timeseries collections.

SpatialIndex = 1

This column has an automatic R-tree spatial index (spatial profile). Exactly one required for spatial collections.

Trait Implementations

impl Clone for ColumnModifier

fn clone(&self) -> ColumnModifier

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ColumnModifier

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ColumnModifier

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<'__msgpack_de> FromMessagePack<'__msgpack_de> for ColumnModifier

fn read<R: Read<'__msgpack_de>>(reader: &mut R) -> Result<Self, Error>

where Self: Sized,

Reads the MessagePack representation of this value from the provided reader.

impl Hash for ColumnModifier

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 ColumnModifier

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl ToMessagePack for ColumnModifier

fn write<W: Write>(&self, writer: &mut W) -> Result<(), Error>

Writes the MessagePack representation of this value into the provided writer.

impl Eq for ColumnModifier

impl StructuralPartialEq for ColumnModifier
