Struct CallbackError 

pub struct CallbackError(/* private fields */);

Failure returned by a caller-provided service (editor, renderer, hydration, etc.). The dynamic boundary preserves the caller’s concrete error for downcasting. Clones share identity; independently constructed errors are distinct.

Implementations

impl CallbackError

pub fn new(error: impl Error + Send + Sync + 'static) -> Self

pub fn downcast_ref<T: Error + 'static>(&self) -> Option<&T>

Trait Implementations

impl Clone for CallbackError

fn clone(&self) -> CallbackError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CallbackError

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

Formats the value using the given formatter.

impl Display for CallbackError

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

Formats the value using the given formatter.

impl Eq for CallbackError

impl Error for CallbackError

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 CallbackError

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

Equality operator ==.

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

Inequality operator !=.
