Enum ErrorCode 

pub enum ErrorCode {
    UnexpectedField,
    Cardinality,
    TypeMismatch,
    NullNotAllowed,
    ShapeMismatch,
}

A stable machine-readable validation failure code, mirroring the Python reference’s Error.code values.

Variants

UnexpectedField

A field was found in the document that is not defined on the record.

Cardinality

The number of field occurrences fell outside [min, max].

TypeMismatch

A value did not match the expected type.

NullNotAllowed

A null value was encountered for a non-nullable field.

ShapeMismatch

A record was encountered where a scalar was expected, or vice-versa.

Implementations

impl ErrorCode

pub fn as_str(&self, family: ErrorFamily) -> &'static str

Stable, family-namespaced error code string per omnist-spec §8.3.1 (<family>.<case>, e.g. validate.shape-mismatch).

TypeMismatch under Materialize is the one case that isn’t a literal materialize.type-mismatch: materialize’s type-mismatch check is specifically “this value can’t be upgraded to the field’s kind without loss or ambiguity,” which §8.3.1 names materialize.inexact-conversion.

Trait Implementations

impl Clone for ErrorCode

fn clone(&self) -> ErrorCode

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for ErrorCode

impl Debug for ErrorCode

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

Formats the value using the given formatter.

impl Eq for ErrorCode

impl PartialEq for ErrorCode

fn eq(&self, other: &ErrorCode) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
