Enum PipelineError 

pub enum PipelineError {
    Source(SourceError),
    Hydration(HydrationError),
    Filter(FilterError),
    Scoring(ScoringError),
    Selection(SelectionError),
    SideEffect(SideEffectError),
}

Top-level pipeline error.

Each variant wraps the error type from a specific stage.

Variants

A candidate source failed.

Hydration(HydrationError)

Hydration failed.

Filter(FilterError)

A filter failed.

Scoring(ScoringError)

Scoring failed.

Selection(SelectionError)

Selection failed.

SideEffect(SideEffectError)

A side effect failed.

Trait Implementations

impl Debug for PipelineError

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

Formats the value using the given formatter.

impl Display for PipelineError

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

Formats the value using the given formatter.

impl Error for PipelineError

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.
