Error types for extension type validation

Variants

InvalidName(InvalidTypeName)

Extension type name is invalid

InvalidAnyTypeVariable

Any type variable is invalid for concrete types

Fields

id: u32

The type variable name

nullability: bool

Whether the type variable is nullable

InvalidParameter(TypeParamError)

Parameter validation failed

InvalidFieldType(String)

Field type is invalid

DuplicateFieldName

Duplicate struct field name

Fields

field_name: String

The duplicated field name

InvalidParameterCount

Type parameter count is invalid for the given type name

Fields

type_name: String

The type name being validated

expected: usize

Expected number of parameters

actual: usize

The actual number of parameters provided

InvalidParameterKind

Type parameter is of the wrong kind for the given position

Fields

type_name: String

The type name being validated

index: usize

Zero-based index of the offending parameter

expected: &'static str

Expected parameter kind (e.g., integer, type)

InvalidParameterValue

Provided parameter value does not fit within the expected bounds

Fields

type_name: String

The type name being validated

index: usize

Zero-based index of the offending parameter

value: i64

Provided parameter value

expected: &'static str

Description of the expected range or type

InvalidParameterRange

Provided parameter value does not fit within the expected bounds

Fields

type_name: String

The type name being validated

index: usize

Zero-based index of the offending parameter

value: i64

Provided parameter value

expected: RangeInclusive<i32>

Description of the expected range or type

StructureCannotBeNullable

Structure representation cannot be nullable

Fields

Trait Implementations

impl Debug for ExtensionTypeError

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

Formats the value using the given formatter.

impl Display for ExtensionTypeError

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

Formats the value using the given formatter.

impl Error for ExtensionTypeError

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<ExtensionTypeError> for SimpleExtensionsError

fn from(source: ExtensionTypeError) -> Self

Converts to this type from the input type.

impl PartialEq for ExtensionTypeError

fn eq(&self, other: &ExtensionTypeError) -> 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 ExtensionTypeError
