Struct mz_persist_client::read::LazyPartStats

pub struct LazyPartStats {
    key: LazyProto<ProtoStructStats>,
}

Aggregate statistics about data contained in a part.

These are “lazy” in the sense that we don’t decode them (or even validate the encoded version) until they’re used.

Fields

key: LazyProto<ProtoStructStats>

Implementations

impl LazyPartStats

pub(crate) fn encode( x: &PartStats, map_proto: impl FnOnce(&mut ProtoStructStats), ) -> Self

pub fn decode(&self) -> PartStats

Decodes and returns PartStats from the encoded representation.

This does not cache the returned value, it decodes each time it’s called.

Trait Implementations

impl Arbitrary for LazyPartStats

type Parameters = ()

The type of parameters that arbitrary_with accepts for configuration of the generated Strategy. Parameters must implement Default.

type Strategy = Map<<PartStats as Arbitrary>::Strategy, fn(_: PartStats) -> LazyPartStats>

The type of Strategy used to generate values of type Self.

fn arbitrary_with(_: ()) -> Self::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self). The strategy is passed the arguments given in args.

fn arbitrary() -> Self::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self).

impl Clone for LazyPartStats

fn clone(&self) -> LazyPartStats

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for LazyPartStats

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for LazyPartStats

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Ord for LazyPartStats

fn cmp(&self, other: &LazyPartStats) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for LazyPartStats

fn eq(&self, other: &LazyPartStats) -> 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 PartialOrd for LazyPartStats

fn partial_cmp(&self, other: &LazyPartStats) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl RustType<Bytes> for LazyPartStats

fn into_proto(&self) -> Bytes

Convert a Self into a Proto value.

fn from_proto(proto: Bytes) -> 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.

impl Serialize for LazyPartStats

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
