Enum EngineError 

pub enum EngineError {
    Compilation(String),
    StreamNotFound(String),
    Sink(SinkError),
    Enrichment(EnrichmentError),
    Store(StoreError),
    Pipeline(String),
}

Top-level error type returned by engine public methods.

Variants

Compilation(String)

Compilation or program-loading error (bad VPL, missing streams, etc.)

StreamNotFound(String)

Referenced stream does not exist.

Sink(SinkError)

Sink I/O or protocol error (async-runtime only).

Enrichment(EnrichmentError)

Enrichment lookup error (async-runtime only).

Store(StoreError)

State-store / persistence error.

Pipeline(String)

Runtime pipeline error (evaluation, pattern matching, etc.)

Trait Implementations

impl Debug for EngineError

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

Formats the value using the given formatter.

impl Display for EngineError

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

Formats the value using the given formatter.

impl Error for EngineError

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.
