pub enum MvError {
    DuplicateName(String),
    SourceNotFound(String),
    CycleDetected(String),
    ViewNotFound(String),
    OperatorNotFound(String),
    HasDependents(String, Vec<String>),
    OperatorError(OperatorError),

}

Errors that can occur during materialized view operations.

Variants

DuplicateName(String)

Attempted to register a view with a name that already exists.

SourceNotFound(String)

A source referenced by the view does not exist.

CycleDetected(String)

Registration would create a dependency cycle.

ViewNotFound(String)

The materialized view was not found.

OperatorNotFound(String)

The operator for a view was not found.

HasDependents(String, Vec<String>)

Cannot drop view because other views depend on it.

OperatorError(OperatorError)

Operator error during processing.

SerializationError(String)

State serialization/deserialization error.

InvalidState(String, MvState)

View is in an invalid state for the requested operation.

WatermarkError(String)

Watermark propagation error.

Trait Implementations

impl Debug for MvError

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

Formats the value using the given formatter.

impl Display for MvError

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

Formats the value using the given formatter.

impl Error for MvError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<MvError> for Error

fn from(source: MvError) -> Self

Converts to this type from the input type.

impl From<OperatorError> for MvError

fn from(source: OperatorError) -> Self

Converts to this type from the input type.
