Trait Implementations

impl Debug for EventBusError

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

Formats the value using the given formatter.

impl Display for EventBusError

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

impl Error for EventBusError

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()
