Enum Error 

pub enum Error {
    Io {
        path: PathBuf,
        source: Error,
    },
    Yaml {
        path: PathBuf,
        source: Error,
    },
    Invalid(String),
    Provider {
        context: String,
        message: String,
        kind: Option<String>,
    },
    Validation(Vec<String>),
}

Everything that can go wrong while loading configuration, parsing skill or test-case definitions, talking to a provider, or running evals.

Variants are grouped so the CLI can map them onto stable exit codes: input problems (Config, Yaml, Skill, Validation) are the user’s to fix; Provider problems are environmental.

Variants

Io

A file the user pointed us at could not be read.

Fields

path: PathBuf

source: Error

Yaml

A YAML document (config or test case) failed to parse.

Fields

path: PathBuf

source: Error

Invalid(String)

A test case or config was syntactically valid YAML but semantically wrong (e.g. a numeric eval with min > max).

Provider

The provider command could not be spawned or did not behave. kind, when set, classifies the failure (e.g. "auth", "rate_limit", "model_not_found", "quota") so the CLI can distinguish a broken environment from a broken skill.

Fields

context: String

message: String

kind: Option<String>

Validation(Vec<String>)

A skill definition failed validation. Carries the human-readable findings so the CLI can print them.

Implementations

impl Error

pub fn provider(context: impl Into<String>, message: impl Display) -> Self

Construct a Error::Provider with no classification.

pub fn provider_classified( context: impl Into<String>, message: impl Display, kind: impl Into<String>, ) -> Self

Construct a classified Error::Provider (e.g. kind = "auth").

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.
