Enum CriterionError 

pub enum CriterionError {
    Expression(ExpressionError),
    Select(SelectError),
    Syntax {
        condition: String,
        message: String,
    },
    Regex {
        condition: String,
        message: String,
    },
    MissingContext(&'static str),
    Unsupported(&'static str),
}

Why a criterion could not be decided.

A criterion that is simply false is not an error — it is the answer.

Variants

Expression(ExpressionError)

A runtime expression in the criterion could not be evaluated.

Select(SelectError)

The criterion’s selector could not be applied.

Syntax

The simple condition does not parse.

Fields

condition: String

The condition as written.

message: String

What the parser objected to.

Regex

The regex condition is not a valid regular expression.

Fields

condition: String

The condition as written.

message: String

What the regex engine said.

MissingContext(&'static str)

A typed criterion arrived without the context it needs.

Unsupported(&'static str)

XPath, which this crate does not evaluate.

Trait Implementations

impl Clone for CriterionError

fn clone(&self) -> CriterionError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CriterionError

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

Formats the value using the given formatter.

Formats the value using the given formatter.

impl Eq for CriterionError

impl Error for CriterionError

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.
