XSD schema error with source location

Variants

XmlError

XML parsing error from quick-xml

Fields

message: String

location: Option<SourceLocation>

StructuralError

Structural error (invalid child element, wrong attributes, etc.)

Fields

constraint: &'static str

message: String

location: Option<SourceLocation>

NamespaceError

Namespace error (undefined prefix, invalid QName, etc.)

Fields

message: String

location: Option<SourceLocation>

FeatureError

Feature gate error (XSD 1.1 feature used in 1.0 mode)

Fields

message: String

location: Option<SourceLocation>

ResolutionError

Schema resolution error (include/import failed)

Fields

message: String

IoError(Error)

I/O error (file not found, permission denied, etc.)

Internal(String)

Internal error (should not happen, indicates a bug)

Implementations

impl SchemaError

pub fn structural( constraint: &'static str, message: impl Into<String>, location: Option<SourceLocation>, ) -> Self

Create a structural error with constraint ID

pub fn namespace( message: impl Into<String>, location: Option<SourceLocation>, ) -> Self

Create a namespace error

pub fn feature( message: impl Into<String>, location: Option<SourceLocation>, ) -> Self

Create a feature gate error

pub fn resolution(message: impl Into<String>) -> Self

Create a resolution error

pub fn xml(message: impl Into<String>, location: Option<SourceLocation>) -> Self

Create an XML parse error

pub fn internal(message: impl Into<String>) -> Self

Create an internal error

pub fn with_location(self, location: SourceLocation) -> Self

Add source location to error if it doesn’t already have one

pub fn is_schema_content_error(&self) -> bool

Returns true for errors that indicate the schema content is invalid (structural, namespace, XML parse, feature-gate errors).

Returns false for resolution/IO errors, which mean the schema could not be located — these are non-fatal during import processing because xs:import schema locations are hints, not requirements.

Trait Implementations

impl Debug for SchemaError

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

Formats the value using the given formatter.

impl Display for SchemaError

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

Formats the value using the given formatter.

impl Error for SchemaError

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<Error> for SchemaError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for SchemaError

Conversion from quick-xml errors

fn from(err: Error) -> Self

Converts to this type from the input type.
