}

Error type for sampler configuration, IO, and persistence failures.

Variants

SourceUnavailable

Source could not be refreshed or reached.

Fields

source_id: SourceId

Identifier of the failing source.

reason: String

Human-readable failure reason.

SourceInconsistent

Source returned internally inconsistent state.

Fields

source_id: SourceId

Identifier of the inconsistent source.

details: String

Details about what invariant was violated.

SplitStore(String)

Split-store persistence or decoding failure.

Io(Error)

Underlying IO error.

Configuration(String)

Invalid or conflicting configuration.

Exhausted(String)

Sampling exhausted eligible candidates for a requested recipe/split.

InvalidWeight

A weight map entry references an unknown source ID or contains a negative value.

Fields

source_id: SourceId

The source ID that triggered the error.

reason: String

Human-readable explanation.

Trait Implementations

impl Debug for SamplerError

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

Formats the value using the given formatter.

impl Display for SamplerError

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

Formats the value using the given formatter.

impl Error for SamplerError

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<Error> for SamplerError

fn from(source: Error) -> Self

Converts to this type from the input type.
