Enum mz_storage_client::types::sources::KeyEnvelope

pub enum KeyEnvelope {
    None,
    Flattened,
    Named(String),
}

Whether and how to include the decoded key of a stream in dataflows

Variants

None

Never include the key in the output row

Flattened

For composite key encodings, pull the fields from the encoding into columns.

Named(String)

Always use the given name for the key.

• For a single-field key, this means that the column will get the given name.
• For a multi-column key, the columns will get packed into a ScalarType::Record, and that Record will get the given name.

Trait Implementations

impl Arbitrary for KeyEnvelope

type Parameters = <String 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<KeyEnvelope>>

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 KeyEnvelope

fn clone(&self) -> KeyEnvelope

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for KeyEnvelope

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for KeyEnvelope

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

Deserialize this value from the given Serde deserializer.

impl PartialEq<KeyEnvelope> for KeyEnvelope

fn eq(&self, other: &KeyEnvelope) -> 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<ProtoKeyEnvelope> for KeyEnvelope

fn into_proto(&self) -> ProtoKeyEnvelope

Convert a Self into a Proto value.

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

Consume and convert a Proto back into a Self value.

impl Serialize for KeyEnvelope

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

Serialize this value into the given Serde serializer.
