Trait Implementations

impl Clone for ExpressionError

fn clone(&self) -> ExpressionError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExpressionError

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

Formats the value using the given formatter.

impl DiagnosticMessage for ExpressionError

fn code(&self) -> usize

fn message(&self) -> String

The subject message of the error.

fn labels(&self) -> Vec<Label>

One or more labels to provide more context for a given error.

fn notes(&self) -> Vec<Note>

One or more notes shown at the bottom of the diagnostic message.

fn severity(&self) -> Severity

The severity of the message.

impl Display for ExpressionError

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

Formats the value using the given formatter.

impl Error for ExpressionError

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.

impl From<&str> for ExpressionError

fn from(message: &str) -> Self

Converts to this type from the input type.

impl From<Error> for ExpressionError

fn from(error: Error) -> Self

Converts to this type from the input type.

impl From<ExpressionError> for Diagnostic

fn from(error: ExpressionError) -> Self

Converts to this type from the input type.

impl From<ExpressionError> for ValueError

fn from(source: ExpressionError) -> Self

Converts to this type from the input type.

impl From<String> for ExpressionError

fn from(message: String) -> Self

Converts to this type from the input type.

impl From<ValueError> for ExpressionError

fn from(err: ValueError) -> Self

Converts to this type from the input type.

impl PartialEq for ExpressionError

fn eq(&self, other: &ExpressionError) -> 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.
