Errors that can occur when working with the object model

Variants

NotFound

The requested object was not found in the registry

Fields

handle: ObjectHandle

The handle refers to an object that has been deleted and recreated

Fields

handle: ObjectHandle

current_generation: u32

TypeMismatch

The object exists but is not of the expected type

Fields

handle: ObjectHandle

expected: ObjectType

actual: ObjectType

MethodNotFound

The requested method does not exist on this object type

Fields

handle: ObjectHandle

method_name: String

InvalidArgument

Invalid argument passed to object method

handle: ObjectHandle

method_name: String

argument: String

reason: String

Implementations

impl ObjectError

pub fn not_found(handle: ObjectHandle) -> Self

Create a NotFound error

pub fn stale_handle(handle: ObjectHandle, current_generation: u32) -> Self

Create a StaleHandle error

pub fn type_mismatch( handle: ObjectHandle, expected: ObjectType, actual: ObjectType, ) -> Self

Create a TypeMismatch error

pub fn method_not_found( handle: ObjectHandle, method_name: impl Into<String>, ) -> Self

Create a MethodNotFound error

pub fn invalid_argument( handle: ObjectHandle, method_name: impl Into<String>, argument: impl Into<String>, reason: impl Into<String>, ) -> Self

Create an InvalidArgument error

Trait Implementations

impl Clone for ObjectError

fn clone(&self) -> ObjectError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ObjectError

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

Formats the value using the given formatter.

impl Display for ObjectError

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

Formats the value using the given formatter.

impl Error for ObjectError

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 PartialEq for ObjectError

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