Errors that can occur during harness operations.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

NotFound(String)

The requested harness was not found on this system.

InvalidPath(PathBuf)

The path is invalid or inaccessible.

EnvVar(VarError)

An environment variable could not be read.

UnsupportedPlatform

The current platform is not supported.

Io(Error)

An I/O error occurred.

UnsupportedMcpConfig

MCP server uses unsupported features for target harness.

Fields

harness: String

The harness that doesn’t support the config.

reason: String

Explanation of what’s unsupported.

BinaryDetection(String)

Binary detection failed due to system error.

UnsupportedScope

The requested scope is not supported by this harness.

Fields

harness: String

scope: String

YamlParse(Error)

YAML parsing failed.

MissingField(String)

A required field is missing from the input.

MissingEnvVar

An environment variable referenced by EnvValue is not set.

Fields

name: String

The name of the environment variable that was not set.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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 Error

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<VarError> for Error

fn from(source: VarError) -> Self

Converts to this type from the input type.
