Variants

InvalidArgumentCount

Fields

expected: usize

actual: usize

UnsupportedTargetType

Fields

target: Value

NotSupportedAsMethod

Fields

method: String

target: Value

UnsupportedKeyType(Value)

Indicates that the script attempted to use a value as a key in a map, but the type of the value was not supported as a key.

UnexpectedType

Fields

got: String

want: String

NoSuchKey(Arc<String>)

Indicates that the script attempted to reference a key on a type that was missing the requested key.

UndeclaredReference(Arc<String>)

Indicates that the script attempted to reference an undeclared variable method, or function.

MissingArgumentOrTarget

Indicates that a function expected to be called as a method, or to be called with at least one parameter.

ValuesNotComparable(Value, Value)

Indicates that a comparison could not be performed.

UnsupportedUnaryOperator(&'static str, Value)

Indicates that an operator was used on a type that does not support it.

UnsupportedBinaryOperator(&'static str, Value, Value)

Indicates that an unsupported binary operator was applied on two values where it’s unsupported, for example list + map.

UnsupportedMapIndex(Value)

Indicates that an unsupported type was used to index a map

UnsupportedListIndex(Value)

Indicates that an unsupported type was used to index a list

UnsupportedIndex(Value, Value)

Indicates that an unsupported type was used to index a list

UnsupportedFunctionCallIdentifierType(Expression)

Indicates that a function call occurred without an Expression::Ident as the function identifier.

UnsupportedFieldsConstruction(Member)

Indicates that a Member::Fields construction was attempted which is not yet supported.

FunctionError

Indicates that a function had an error during execution.

Fields

function: String

message: String

Trait Implementations

impl Clone for ExecutionError

fn clone(&self) -> ExecutionError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

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, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for ExecutionError

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<ExecutionError> for ResolveResult

fn from(value: ExecutionError) -> Self

Converts to this type from the input type.

impl PartialEq for ExecutionError

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

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

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

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