Struct AsyncError 

pub struct AsyncError<E: Error + 'static> { /* private fields */ }

Wraps an error with optional context.

Implementations

impl<E: Error + 'static> AsyncError<E>

pub fn new(error: E) -> Self

Creates a new error wrapper without context.

pub fn with_context(self, context: String) -> Self

Adds context to the error.

If the hooks feature is enabled, hooks may be triggered.

pub fn inner_error(&self) -> &E

Returns a reference to the inner error.

pub fn context(&self) -> Option<&str>

Returns the context string, if any.

pub fn invoke_hooks_once(&self) -> bool

Returns true if hooks have not been invoked yet, and marks them as invoked.

Trait Implementations

impl<E: Debug + Error + 'static> Debug for AsyncError<E>

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

Formats the value using the given formatter.

impl<E: Error + 'static> Display for AsyncError<E>

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

Formats the value using the given formatter.

impl<E: Error + 'static> Error for AsyncError<E>

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.
