Struct rune::QueryError

pub struct QueryError { /* fields omitted */ }

An error raised during querying.

Implementations

impl QueryError

pub fn new<S, K>(spanned: S, kind: K) -> Self where
    S: Spanned,
    QueryErrorKind: From<K>, 

Construct a new scope error.

pub fn msg<S>(spanned: S, message: &'static str) -> Self where
    S: Spanned, 

Construct an custom error.

This should be used for programming invariants of the encoder which are broken for some reason.

pub fn kind(&self) -> &QueryErrorKind

Get the kind of the error.

pub fn into_kind(self) -> QueryErrorKind

Convert into the kind of the error.

Trait Implementations

impl Debug for QueryError

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

Formats the value using the given formatter.

impl Display for QueryError

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

Formats the value using the given formatter.

impl Error for QueryError

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

pub fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

pub fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

pub fn cause(&self) -> Option<&dyn Error>

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
