Errors from owned document parsing, identity validation, and mutation.

Variants

Policy(PolicyViolation)

The immutable operation policy contains invalid resource limits.

DocumentTooLarge

The input exceeds the active XML document byte limit.

Fields

maximum: usize

Maximum accepted byte length.

actual: usize

Actual byte length.

DocumentTooDeep

The input exceeds the active XML element nesting limit.

Fields

maximum: usize

Maximum accepted element nesting depth.

actual: usize

First observed element nesting depth beyond the limit.

Parse(Error)

The XML parser rejected the document.

BackendParse

The selected parser backend rejected the document.

Fields

backend: &'static str

Compile-time selected parser backend.

message: String

Stable human-readable parser diagnostic.

ForeignIdentity

An identity belongs to another document.

StaleIdentity

An identity belongs to an earlier document generation.

Fields

identity: u64

Generation captured by the identity.

current: u64

Current document generation.

MissingNode

The node no longer exists in the current parsed tree.

TargetNotElement

A mutation target is not an element.

InvalidReplacement(String)

Replacement content does not satisfy the requested structural shape.

IdentityExhausted

Process-local document provenance space is exhausted.

ProjectedNodeLimit

A projected mutation exceeds the caller’s active node ceiling.

Fields

maximum: usize

Maximum accepted parser node count.

Trait Implementations

impl Debug for XmlDocumentError

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

Formats the value using the given formatter.

impl Display for XmlDocumentError

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

Formats the value using the given formatter.

impl Error for XmlDocumentError

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.
