Enum StatValue 

pub enum StatValue {
    Int(i64),
    UInt(u64),
    Float(f64),
    Bytes(Vec<u8>),
    TimestampNs(i64),
}

A typed min or max value.

Variants

Int(i64)

Signed integer value (for the signed integer dtypes).

UInt(u64)

Unsigned integer value (for the unsigned integer dtypes).

Float(f64)

Floating-point value (for Float32/Float64).

Bytes(Vec<u8>)

String or binary: raw bytes in lexicographic order.

TimestampNs(i64)

Nanoseconds since the Unix epoch — matches DType::TimestampNs.

Trait Implementations

impl Archive for StatValue

where i64: Archive, u64: Archive, f64: Archive, Vec<u8>: Archive,

type Archived = ArchivedStatValue

The archived representation of this type.

type Resolver = StatValueResolver

The resolver for this type. It must contain all the additional information from serializing needed to make the archived type from the normal type.

fn resolve( &self, resolver: <Self as Archive>::Resolver, out: Place<<Self as Archive>::Archived>, )

Creates the archived version of this value at the given position and writes it to the given output.

const COPY_OPTIMIZATION: CopyOptimization<Self> = _

An optimization flag that allows the bytes of this type to be copied directly to a writer instead of calling serialize.

impl Clone for StatValue

fn clone(&self) -> StatValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StatValue

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

Formats the value using the given formatter.

impl<__D: Fallible + ?Sized> Deserialize<StatValue, __D> for Archived<StatValue>

where i64: Archive, <i64 as Archive>::Archived: Deserialize<i64, __D>, u64: Archive, <u64 as Archive>::Archived: Deserialize<u64, __D>, f64: Archive, <f64 as Archive>::Archived: Deserialize<f64, __D>, Vec<u8>: Archive, <Vec<u8> as Archive>::Archived: Deserialize<Vec<u8>, __D>,

fn deserialize( &self, deserializer: &mut __D, ) -> Result<StatValue, <__D as Fallible>::Error>

Deserializes using the given deserializer

impl PartialEq for StatValue

fn eq(&self, other: &StatValue) -> 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<__S: Fallible + ?Sized> Serialize<__S> for StatValue

where i64: Serialize<__S>, u64: Serialize<__S>, f64: Serialize<__S>, Vec<u8>: Serialize<__S>,

fn serialize( &self, serializer: &mut __S, ) -> Result<<Self as Archive>::Resolver, <__S as Fallible>::Error>

Writes the dependencies for the object and returns a resolver that can create the archived type.
