pub enum AddBackendError {
    DuplicateNamespace(String),
    AmbiguousPrefix {
        new_namespace: String,
        existing_namespace: String,
    },
    Connect(Error),
    Initialize(Error),
}

Namespace requested for the backend being added.

existing_namespace: String

Existing namespace whose prefix would conflict.

Connect(Error)

Failed to connect the transport.

Initialize(Error)
