Errors thrown during operations on Extensions.

Variants

FuncDoesNotExist

Tried to call a function that doesn’t exist

Fields

name: Name

Name of the function that doesn’t exist

HasNoType

Attempted to typecheck an expression that had no type

Fields

name: Name

Name of the function that returns no type

FuncMultiplyDefined

Tried to call a function but it was defined multiple times (e.g., by multiple different extensions)

Fields

name: Name

Name of the function that is multiply defined

num_defs: usize

How many times that function is defined

MultipleConstructorsSameSignature

Two extension constructors (in the same or different extensions) had exactly the same type signature. This is currently not allowed.

Fields

return_type: Box<SchemaType>

return type of the shared constructor signature

arg_type: Box<SchemaType>

argument type of the shared constructor signature

Trait Implementations

impl Clone for ExtensionsError

fn clone(&self) -> ExtensionsError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ExtensionsError

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

Formats the value using the given formatter.

impl Display for ExtensionsError

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

Formats the value using the given formatter.

impl Error for ExtensionsError

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<ExtensionsError> for EvaluationError

fn from(source: ExtensionsError) -> Self

Converts to this type from the input type.

impl From<ExtensionsError> for JsonDeserializationError

fn from(source: ExtensionsError) -> Self

Converts to this type from the input type.

impl PartialEq for ExtensionsError

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