Things that may go wrong during execution of a compiled script.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

BoolNoArithmetic

No arithemetic with boolean for now.

Environment

Passthrough environment errors.

Fields

source: Error

The original error.

NilValue

Nil does not allow anything.

NoBoolean

Expected Boolean, got something else.

Fields

value: Arc<str>

The faulty value.

NoComparison

Comparisons (greater, less) only with numeric values.

NoInteger

Expected Integer, got something else.

Fields

value: Arc<str>

The faulty value.

NoNumber

Expected a numerical value, got something else.

Fields

value: Arc<str>

The faulty value.

StackOverflow

Stack overflow.

OnlyAdd

Strings only allow additions.

Unreachable

This code line never should have been reached.

Fields

file: Arc<str>

The faulty file.

line: u32

The faulty line.

Trait Implementations

impl Debug for ExecutionError

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

Formats the value using the given formatter.

impl Display for ExecutionError

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

Formats the value using the given formatter.

impl Error for ExecutionError

Currently the default implementation is sufficient.

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<Error> for ExecutionError

fn from(error: Error) -> Self

Converts to this type from the input type.

impl From<ExecutionError> for Error

fn from(source: ExecutionError) -> Self

Converts to this type from the input type.
