Enum Error 

pub enum Error {
    Codec(CodecError),
    StorageShapeMismatch {
        record: RecordKind,
        reason: ShapeMismatchReason,
    },
    InvalidDomainValue {
        field: StorageField,
        reason: String,
    },
}

Errors raised while validating storage records, codecs, or domain-to-storage projection.

Variants

Codec(CodecError)

Wraps a storage JSON codec failure without losing the underlying source error.

StorageShapeMismatch

Signals that a flattened record populated fields inconsistent with its discriminator.

Fields

record: RecordKind

Record family whose flattened storage shape failed validation.

reason: ShapeMismatchReason

Human-readable or typed reason explaining why storage conversion failed.

InvalidDomainValue

Signals that a domain value cannot be represented safely in storage.

Fields

field: StorageField

Storage field whose value failed projection or validation.

reason: String

Human-readable reason explaining why the storage projection was unsafe.

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<CodecError> for Error

fn from(source: CodecError) -> Self

Converts to this type from the input type.
