Trait Implementations

impl Clone for BytesStats

fn clone(&self) -> BytesStats

Returns a copy of the value.

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

Performs copy-assignment from source.

impl ColumnStats for BytesStats

type Ref<'a> = &'a [u8]

Type returned as the stat bounds.

fn lower<'a>(&'a self) -> Option<Self::Ref<'a>>

An inclusive lower bound on the data contained in the column, if known.

fn upper<'a>(&'a self) -> Option<Self::Ref<'a>>

Same as Self::lower but an (also inclusive) upper bound.

fn none_count(&self) -> usize

The number of Nones if this column is optional or 0 if it isn’t.

impl Debug for BytesStats

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

Formats the value using the given formatter.

impl DynStats for BytesStats

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 RustType<ProtoBytesStats> for BytesStats

fn into_proto(&self) -> ProtoBytesStats

Convert a Self into a Proto value.

fn from_proto(proto: ProtoBytesStats) -> 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.
