Trait Implementations

impl<E: Debug, C: Debug> Debug for ErrorContext<E, C>

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

Formats the value using the given formatter.

impl<E, C> Display for ErrorContext<E, C>

where E: Display, C: Display,

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

Formats the value using the given formatter.

impl<E, C> Error for ErrorContext<E, C>

where E: Error, C: Display + Debug,

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

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<E, C, C2> WithContext<C2> for ErrorContext<E, C>

type ContextError = ErrorContext<ErrorContext<E, C>, C2>

fn with_context(self, context: C2) -> ErrorContext<ErrorContext<E, C>, C2>
