Struct MetadataValidationError 

pub struct MetadataValidationError { /* private fields */ }

Aggregate error returned by schema-level validation APIs.

Unlike single-entry metadata accessors, schema validation can discover multiple independent issues in one pass. This type preserves all collected MetadataError values so callers can report or fix them together. Debug and Display share a bounded diagnostic traversal; use Self::issues to inspect the complete collection independently of formatting limits.

Examples

use qubit_metadata::{MetadataError, MetadataValidationError};

let error = MetadataValidationError::from_issue(MetadataError::MissingKey("tenant".into()));
assert_eq!(error.len(), 1);

Implementations

impl MetadataValidationError

pub fn from_issue(issue: MetadataError) -> Self

Creates an aggregate validation error from one issue.

Parameters

• issue - Validation issue to store.

Returns

An aggregate error containing exactly one issue.

pub fn from_issues(issues: Vec<MetadataError>) -> Option<Self>

Creates an aggregate validation error from a non-empty issue list.

Returns None when issues is empty because an empty validation error has no actionable meaning.

Parameters

• issues - Validation issues to aggregate.

Returns

Some aggregate error for a non-empty list; otherwise, None.

pub fn issues(&self) -> &[MetadataError]

Returns the collected validation issues.

Returns

The issues in discovery order.

pub fn len(&self) -> usize

Returns the number of collected validation issues.

Returns

The issue count.

pub fn into_issues(self) -> Vec<MetadataError>

Converts this aggregate error into its collected issues.

Returns

The owned issues in discovery order.

Trait Implementations

impl Clone for MetadataValidationError

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 MetadataValidationError

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

Formats a bounded diagnostic summary using the strict policy.

Parameters

• formatter - Destination receiving the diagnostic summary.

impl Display for MetadataValidationError

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

Formats the issue count and a bounded diagnostic view of the issues.

The complete issue collection remains available through issues(). Exhausted diagnostic budgets produce an explicit incomplete marker.

Parameters

• formatter - Formatter receiving the validation summary.

impl Eq for MetadataValidationError

impl Error for MetadataValidationError

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 PartialEq for MetadataValidationError

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

Equality operator ==.

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

Inequality operator !=.

impl Redact for MetadataValidationError

fn write_redacted(&self, writer: &mut RedactionWriter<'_>)

Writes admitted issues under one cumulative diagnostic budget.

Issue text is diagnostic data, not a confidentiality boundary for arbitrary keys or application-supplied error messages.

Parameters

• writer - Destination sharing output, node, and collection budgets.
