Enum ValidationError 

pub enum ValidationError {
    SchemaMismatch {
        path: String,
        schema: String,
        details: String,
    },
    DuplicateId {
        path: String,
        index: usize,
        id: String,
    },
    Deserialize {
        path: String,
        message: String,
    },
}

A validation failure. Each variant carries the path of the artifact under inspection so messages are actionable.

(The field is named path rather than source because thiserror reserves a field named source for the underlying std::error::Error cause.)

Variants

SchemaMismatch

data failed structural validation against the named schema. details is one <instance-path> <message> line per failure.

Fields

path: String

schema: String

details: String

DuplicateId

Two evals share an id — a uniqueness constraint JSON Schema (draft-07) can’t express, so it is checked by hand after structural validation.

Fields

path: String

index: usize

id: String

Deserialize

The data matched the schema but could not be deserialized into the requested type — a contract drift between schema and Rust type.

Fields

path: String

message: String

Trait Implementations

impl Debug for ValidationError

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

Formats the value using the given formatter.

impl Display for ValidationError

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

Formats the value using the given formatter.

impl Error for ValidationError

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<ValidationError> for DescriptorError

fn from(source: ValidationError) -> Self

Converts to this type from the input type.

impl From<ValidationError> for PipelineError

fn from(source: ValidationError) -> Self

Converts to this type from the input type.
