Enum QueryError 

pub enum QueryError {
    NoMatch,
    Ambiguous(usize),
}

Why a strict lookup failed — the non-panicking form used by machine-driven harnesses (scenario scripts).

Variants

NoMatch

Nothing matched.

Ambiguous(usize)

Several nodes matched (the count) — refine the query.

Trait Implementations

impl Clone for QueryError

fn clone(&self) -> QueryError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for QueryError

impl Debug for QueryError

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

Formats the value using the given formatter.

impl Display for QueryError

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

Formats the value using the given formatter.

impl Eq for QueryError

impl PartialEq for QueryError

fn eq(&self, other: &QueryError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
