Implementations

impl RuntimeError

pub fn undefined_variable(name: impl Into<String>) -> Self

Create an UndefinedVariable error without position.

pub fn undefined_variable_at( name: impl Into<String>, position: Position, ) -> Self

Create an UndefinedVariable error with position.

pub fn undefined_function(name: impl Into<String>) -> Self

Create an UndefinedFunction error without position.

pub fn type_mismatch(message: impl Into<String>) -> Self

Create a TypeMismatch error without position.

pub fn type_mismatch_at(message: impl Into<String>, position: Position) -> Self

Create a TypeMismatch error with position.

pub fn invalid_argument(message: impl Into<String>) -> Self

Create an InvalidArgument error.

pub fn wrong_argument_count(expected: usize, actual: usize) -> Self

Create a WrongArgumentCount error without position.

Trait Implementations

impl Clone for RuntimeError

fn clone(&self) -> RuntimeError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RuntimeError

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

Formats the value using the given formatter.

impl Display for RuntimeError

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

Formats the value using the given formatter.

impl Error for RuntimeError

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<RuntimeError> for FiddlerError

fn from(source: RuntimeError) -> Self

Converts to this type from the input type.

impl PartialEq for RuntimeError

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

impl StructuralPartialEq for RuntimeError
