Rejection while constructing or embedding RNG provenance.

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.

EmptyField

A required textual identity field is empty or whitespace-only.

Fields

field: &'static str

Rejected stable field name.

DuplicateNamespace

A metadata map already contains a record for the namespace.

Fields

namespace: String

Repeated application namespace.

InvalidMetadataShape

The reserved metadata entry is not an object indexed by namespace.

InvalidStoredRecord

A stored namespaced value does not decode as an RNG record.

Fields

namespace: String

Namespace selected by the caller.

source: Error

JSON type or field failure.

NamespaceMismatch

The metadata index and embedded record namespace disagree.

Fields

index: String

Namespace used as the metadata object key.

record: String

Namespace embedded in the record.

Trait Implementations

impl Debug for RngRecordError

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

Formats the value using the given formatter.

impl Display for RngRecordError

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

Formats the value using the given formatter.

impl Error for RngRecordError

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.
