Enum mz_persist_types::stats::ColumnStatKinds

pub enum ColumnStatKinds {
    Primitive(PrimitiveStatsVariants),
    Struct(StructStats),
    Bytes(BytesStats),
    None,
}

All of the kinds of statistics that we support.

Variants

Primitive(PrimitiveStatsVariants)

Primitive stats that maintin just an upper and lower bound.

Struct(StructStats)

Statistics for objects with multiple fields.

Bytes(BytesStats)

Statistics about a column of binary data.

None

Maintain no statistics for a given column.

Trait Implementations

impl Clone for ColumnStatKinds

fn clone(&self) -> ColumnStatKinds

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ColumnStatKinds

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

Formats the value using the given formatter.

impl DynStats for ColumnStatKinds

fn debug_json(&self) -> Value

Formats these statistics for use in INSPECT SHARD and debugging.

fn into_columnar_stats(self) -> ColumnarStats

Return self as ColumnarStats.

fn type_name(&self) -> &'static str

Returns the name of the erased type for use in error messages.

impl From<BytesStats> for ColumnStatKinds

fn from(value: BytesStats) -> Self

Converts to this type from the input type.

impl From<PrimitiveStats<Vec<u8>>> for ColumnStatKinds

fn from(value: PrimitiveStats<Vec<u8>>) -> Self

Converts to this type from the input type.

impl From<StructStats> for ColumnStatKinds

fn from(value: StructStats) -> Self

Converts to this type from the input type.

impl<T: Into<PrimitiveStatsVariants>> From<T> for ColumnStatKinds

fn from(value: T) -> Self

Converts to this type from the input type.

impl RustType<Kind> for ColumnStatKinds

fn into_proto(&self) -> Kind

Convert a Self into a Proto value.

fn from_proto(proto: Kind) -> Result<Self, TryFromProtoError>

Consume and convert a Proto back into a Self value.

fn into_proto_owned(self) -> Proto

A zero clone version of Self::into_proto that types can optionally implement, otherwise, the default implementation delegates to Self::into_proto.
