Enum UpsertError

pub enum UpsertError {
    KeyDecode(DecodeError),
    Value(UpsertValueError),
    NullKey(UpsertNullKeyError),
}

An error that can be retracted by a future message using upsert logic.

Variants

KeyDecode(DecodeError)

Wrapper around a key decoding error. We use this instead of emitting the underlying DataflowError::DecodeError because with only the underlying error, we can’t distinguish between an error with the key and an error with the value.

It is necessary to distinguish them because the necessary record to retract them is different. (K, <errored V>) is retracted by (K, null), whereas (<errored K>, anything) is retracted by ("bytes", null), where “bytes” is the string that failed to correctly decode as a key.

Value(UpsertValueError)

Wrapper around an error related to the value.

NullKey(UpsertNullKeyError)

Trait Implementations

impl Arbitrary for UpsertError

type Parameters = (<DecodeError as Arbitrary>::Parameters, <UpsertValueError as Arbitrary>::Parameters, <UpsertNullKeyError 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<UpsertError>>

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 UpsertError

fn clone(&self) -> UpsertError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for UpsertError

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for UpsertError

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for UpsertError

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

Formats the value using the given formatter.

impl Hash for UpsertError

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for UpsertError

fn cmp(&self, other: &UpsertError) -> 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,

Restrict a value to a certain interval.

impl PartialEq for UpsertError

fn eq(&self, other: &UpsertError) -> 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 UpsertError

fn partial_cmp(&self, other: &UpsertError) -> 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<ProtoUpsertError> for UpsertError

fn into_proto(&self) -> ProtoUpsertError

Convert a Self into a Proto value.

fn from_proto(proto: ProtoUpsertError) -> 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 UpsertError

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
