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 From<HealthCheckError> for RecycleError<ConnectionError>

fn from(err: HealthCheckError) -> Self

Converts to this type from the input type.
