Enum mz_storage_client::types::sources::UnplannedSourceEnvelope

pub enum UnplannedSourceEnvelope {
    None(KeyEnvelope),
    Debezium(DebeziumEnvelope),
    Upsert(UpsertStyle),
    CdcV2,
}

UnplannedSourceEnvelope is a SourceEnvelope missing some information. This information is obtained in UnplannedSourceEnvelope::desc, where UnplannedSourceEnvelope::into_source_envelope creates a full SourceEnvelope

Variants

Implementations

impl UnplannedSourceEnvelope

fn into_source_envelope(
    self,
    key: Option<Vec<usize>>,
    key_arity: Option<usize>,
    source_arity: Option<usize>
) -> SourceEnvelope

Transforms an UnplannedSourceEnvelope into a SourceEnvelope

Panics if the input envelope is UnplannedSourceEnvelope::Upsert and key is not passed as Some

pub fn desc(
    self,
    key_desc: Option<RelationDesc>,
    value_desc: RelationDesc,
    metadata_desc: RelationDesc
) -> Result<(SourceEnvelope, RelationDesc)>

Computes the output relation of this envelope when applied on top of the decoded key and value relation desc

Trait Implementations

impl Clone for UnplannedSourceEnvelope

fn clone(&self) -> UnplannedSourceEnvelope

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for UnplannedSourceEnvelope

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for UnplannedSourceEnvelope

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

Deserialize this value from the given Serde deserializer.

impl PartialEq<UnplannedSourceEnvelope> for UnplannedSourceEnvelope

fn eq(&self, other: &UnplannedSourceEnvelope) -> 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 Serialize for UnplannedSourceEnvelope

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

Serialize this value into the given Serde serializer.
