Struct UnknownLineage 

pub struct UnknownLineage<V>(pub <V as Identities>::Lineage)
where
    V: Identities;

A plain lineage, or an epoch of one, that the instance cannot answer for: another instance’s, or one ended or retired (DI-D-40). The instance keeps no memory of a lineage once it is gone, as it keeps none of a resolved failure.

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
