Enum mz_storage_client::types::sources::encoding::SourceDataEncoding

pub enum SourceDataEncoding {
    Single(DataEncoding),
    KeyValue {
        key: DataEncoding,
        value: DataEncoding,
    },
}

A description of how to interpret data from various sources

Almost all sources only present values as part of their records, but Kafka allows a key to be associated with each record, which has a possibly independent encoding.

Variants

Single(DataEncoding)

KeyValue

Fields

key: DataEncoding

value: DataEncoding

Implementations

impl SourceDataEncoding

pub fn key_ref(&self) -> Option<&DataEncoding>

pub fn value(self) -> DataEncoding

Return either the Single encoding if this was a SourceDataEncoding::Single, else return the value encoding

pub fn value_ref(&self) -> &DataEncoding

pub fn desc(&self) -> Result<(Option<RelationDesc>, RelationDesc), Error>

Trait Implementations

impl Arbitrary for SourceDataEncoding

type Parameters = (<DataEncoding as Arbitrary>::Parameters, (<DataEncoding as Arbitrary>::Parameters, <DataEncoding as Arbitrary>::Parameters))

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

type Strategy = Union<BoxedStrategy<SourceDataEncoding>>

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

fn arbitrary_with(_top: Self::Parameters) -> 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 SourceDataEncoding

fn clone(&self) -> SourceDataEncoding

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SourceDataEncoding

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SourceDataEncoding

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where
    __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq<SourceDataEncoding> for SourceDataEncoding

fn eq(&self, other: &SourceDataEncoding) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl RustType<ProtoSourceDataEncoding> for SourceDataEncoding

fn into_proto(&self) -> ProtoSourceDataEncoding

Convert a Self into a Proto value.

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

Consume and convert a Proto back into a Self value.

impl Serialize for SourceDataEncoding

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

Serialize this value into the given Serde serializer.
