Enum ValidatorRegistryError 

#[non_exhaustive]
pub enum ValidatorRegistryError {
    DuplicateId {
        id: &'static str,
        sources: Vec<RegistrationSource>,
    },
    InvalidDescriptor {
        id: ValidatorId,
        registration_source: RegistrationSource,
        kind: BindErrorKind,
        dependency: Option<String>,
    },
}

Failure while freezing a validator registry.

Examples

use qubit_validator::{BindErrorKind, RegistrationSource, ValidatorId, ValidatorRegistryError};

let error = ValidatorRegistryError::InvalidDescriptor {
    id: ValidatorId::new("text.required"),
    registration_source: RegistrationSource::new("rules", "rules::text", "src/text.rs", 12),
    kind: BindErrorKind::InvalidDeclaration,
    dependency: None,
};
assert!(error.to_string().contains("invalid descriptor"));

Source compatibility

The enum-level non_exhaustive attribute requires external matches to include a wildcard arm for future variants. It does not prevent external callers from constructing the current variants or matching all of their fields. Construction must supply every field of the selected variant. Patterns may use .. to ignore fields they do not need.

Adding a field to an existing variant can break external construction or complete field patterns and must be evaluated as a source-compatibility change separately from adding an enum variant.

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.

DuplicateId

Multiple registrations claim one stable ID.

Fields

id: &'static str

Conflicting stable ID.

sources: Vec<RegistrationSource>

Registration sources in deterministic order.

InvalidDescriptor

A registration contains an invalid descriptor declaration.

Fields

id: ValidatorId

Validator identifier.

registration_source: RegistrationSource

Registration source.

kind: BindErrorKind

Declaration error kind.

dependency: Option<String>

Dependency name attached to the declaration error, if present.

This stores only names declared in the descriptor, not runtime dependency values. The name is available through pattern matching but is omitted from the default debug representation.

Trait Implementations

impl Clone for ValidatorRegistryError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ValidatorRegistryError

fn fmt(&self, formatter: &mut Formatter<'_>) -> FmtResult

Formats registration metadata without exposing dependency names.

Parameters

• self is the registry error whose registration metadata is formatted.
• formatter is the destination supplied by the caller of Debug::fmt.

impl Display for ValidatorRegistryError

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

Formats the value using the given formatter.

impl Error for ValidatorRegistryError

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.
