Errors that can occur during benchmark operations.

Variants

Yaml

A YAML file failed to parse.

Fields

path: PathBuf

The file being parsed.

source: Error

The underlying serde-yaml error.

Io(Error)

An underlying I/O error (filesystem access, reading cache files, etc.).

Download

Downloading a relation file failed.

Fields

url: String

URL that was being fetched.

source: Error

Underlying reqwest error.

NotFound(String)

A benchmark with the requested name does not exist.

Invalid

The benchmark definition is structurally invalid (see BenchmarkDefinition::validate).

Fields

name: String

The benchmark name as declared in the YAML.

reason: String

Human-readable description of the invariant that was violated.

NoCacheDir

The platform cache directory could not be determined.

SpecDrift

A generator-spec YAML’s parameters disagree with the cached meta.json’s spec_hash. Returned by the materialization layer to prevent silently re-running an expensive pipeline.

Fields

name: String

Benchmark name.

expected_hash: String

Spec hash computed from the workspace YAML at this invocation.

actual_hash: String

Spec hash recorded in the cached meta.json.

hint: String

Resolution hint shown to the user.

Trait Implementations

impl Debug for BenchError

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

Formats the value using the given formatter.

impl Display for BenchError

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

Formats the value using the given formatter.

impl Error for BenchError

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 BenchError

fn from(source: Error) -> Self

Converts to this type from the input type.
