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

pub enum SourceDataEncoding<C: ConnectionAccess = InlinedConnection> {
    Single(DataEncoding<C>),
    KeyValue {
        key: DataEncoding<C>,
        value: DataEncoding<C>,
    },
}

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<C>)

KeyValue

Fields

key: DataEncoding<C>

value: DataEncoding<C>

Implementations

impl<C: ConnectionAccess> SourceDataEncoding<C>

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

pub fn value(self) -> DataEncoding<C>

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

pub fn value_ref(&self) -> &DataEncoding<C>

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

Trait Implementations

impl<C: ConnectionAccess + Arbitrary> Arbitrary for SourceDataEncoding<C>

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

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<C: Clone + ConnectionAccess> Clone for SourceDataEncoding<C>

fn clone(&self) -> SourceDataEncoding<C>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<C: Debug + ConnectionAccess> Debug for SourceDataEncoding<C>

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

Formats the value using the given formatter.

impl<'de, C> Deserialize<'de> for SourceDataEncoding<C>where C: Deserialize<'de> + ConnectionAccess,

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

Deserialize this value from the given Serde deserializer.

impl<R: ConnectionResolver> IntoInlineConnection<SourceDataEncoding<InlinedConnection>, R> for SourceDataEncoding<ReferencedConnection>

fn into_inline_connection(self, r: R) -> SourceDataEncoding

impl<C: PartialEq + ConnectionAccess> PartialEq<SourceDataEncoding<C>> for SourceDataEncoding<C>

fn eq(&self, other: &SourceDataEncoding<C>) -> 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<C> Serialize for SourceDataEncoding<C>where C: Serialize + ConnectionAccess,

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

Serialize this value into the given Serde serializer.
