Type errors accumulated during validation.

These represent mismatches between the document and schema. Validation continues after recording these errors.

NoVariantMatched

No variant matched in an untagged union validation.

This error occurs when all variants of a union are tried and none succeeds. When available, best_match provides detailed information about which variant came closest to matching and why it failed.

For tagged unions (with $variant or VariantRepr), validation errors are reported directly instead of wrapping them in NoVariantMatched.

Implementations

impl ValidationError

pub fn node_ids(&self) -> (NodeId, SchemaNodeId)

Get the node IDs associated with this error.

pub fn depth(&self) -> usize

Calculate the depth of this error (path length).

Deeper errors indicate that validation got further into the structure before failing, suggesting a better match.

pub fn priority_score(&self) -> u8

Get priority score for error type (higher = more indicative of mismatch).

Used for selecting the “best” variant error when multiple variants fail with similar depth and error counts.

Trait Implementations

impl Clone for ValidationError

fn clone(&self) -> ValidationError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ValidationError

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

Formats the value using the given formatter.

impl Display for ValidationError

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

Formats the value using the given formatter.

impl Error for ValidationError

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 ValidationError

fn eq(&self, other: &ValidationError) -> 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.
