Enum SelectError 

pub enum SelectError {
    Expression(ExpressionError),
    Malformed {
        selector: String,
        kind: &'static str,
        message: String,
    },
    Empty {
        selector: String,
        context: String,
    },
    Unsupported(&'static str),
}

Why a value could not be produced.

Variants

Expression(ExpressionError)

A runtime expression in the value could not be evaluated.

Malformed

The selector expression itself is malformed.

Fields

selector: String

The expression as written.

kind: &'static str

The language it was read as.

message: String

What the parser said.

Empty

The selector is valid but picked nothing.

Fields

selector: String

The expression as written.

context: String

The runtime expression naming what it applied to.

Unsupported(&'static str)

XPath: no engine here, and pretending otherwise would be worse.

Trait Implementations

impl Clone for SelectError

fn clone(&self) -> SelectError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SelectError

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

Formats the value using the given formatter.

impl Display for SelectError

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

Formats the value using the given formatter.

impl Eq for SelectError

impl Error for SelectError

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.
