Enum SchematronEvalError 

pub enum SchematronEvalError {
    Parse(ParseError),
    Eval(EvalError),
    ContextNotNodeSet {
        context: String,
    },
    UnknownPhase {
        phase: String,
    },
}

An error evaluating a Schema against a document.

Distinct from xpath_eval::EvalError (note the different name) so callers can use both without a collision. Wraps both failure modes xpath-eval can produce — a context/test string that is not syntactically valid XPath (SchematronEvalError::Parse), and a well-formed expression that fails at evaluation time (SchematronEvalError::Eval) — plus one failure mode specific to this crate’s context-as-path-selection simplification: a context expression that parses but does not evaluate to a node-set (SchematronEvalError::ContextNotNodeSet).

Variants

Parse(ParseError)

A context or test expression failed to parse as XPath.

Eval(EvalError)

A well-formed expression failed at evaluation time.

ContextNotNodeSet

A rule’s context, once evaluated as descendant-or-self::node()/ prefixed onto the raw context string, did not evaluate to a node-set (e.g. it evaluated to a number or string instead) — context must be a location-path/node-set expression.

Fields

context: String

UnknownPhase

evaluate_with_phase was called with a phase_id that does not match any Schema.phases[_].id (or Schema.default_phase names such an unknown phase).

Fields

phase: String

Trait Implementations

impl Error for SchematronEvalError

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
