Enum RaftError 

pub enum RaftError<NID, E = Infallible>
where
    NID: NodeId,
{
    APIError(E),
    Fatal(Fatal<NID>),
}

RaftError is returned by API methods of Raft.

It is either a Fatal error indicating that Raft is no longer running, such as underlying IO error, or an API error E.

Variants

APIError(E)

Fatal(Fatal<NID>)

Implementations

👎Deprecated since 1.42.0:

use the Display impl or to_string()

👎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<NID, E> From<Fatal<NID>> for RaftError<NID, E>

where NID: NodeId,
