Why a tuning proposal could not be produced.

Variants

InvalidConfig(String)

A reviewability or inference bound is invalid.

NoFalsePositives

No false-positive events were provided.

NoTruePositives

No true-positive events were provided.

NonFiringExemplars

Some labeled exemplars do not fire the target rule before filtering.

Fields

fp: Vec<usize>

False-positive indexes that did not fire.

tp: Vec<usize>

True-positive indexes that did not fire.

NoCandidateFields(usize)

No stable scalar field could be profiled.

NoCleanSeparator

No verified separator protected every TP and covered the required FPs.

Fields

closest: Vec<String>

Highest-ranked fields considered.

blocking_tp: Vec<usize>

True positives suppressed by the closest candidate.

uncovered_fp: Vec<usize>

False positives not covered by the partial proposal.

Internal

Emitted YAML failed its own parse, lint, compile, or verification pass.

Fields

stage: String

Failing stage.

message: String

Underlying message.

Trait Implementations

impl Debug for TuneError

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

Formats the value using the given formatter.

impl Display for TuneError

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

Formats the value using the given formatter.

impl Error for TuneError

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.
