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<E, M> From<MiddlewareError<E, M>> for Error

where E: Into<Self>, M: Into<Self>,

fn from(err: MiddlewareError<E, M>) -> Self

Converts to this type from the input type.
