Struct pallet_session::FindAccountFromAuthorIndex

source · 
pub struct FindAccountFromAuthorIndex<T, Inner>(/* private fields */);
Expand description

Wraps the author-scraping logic for consensus engines that can recover the canonical index of an author. This then transforms it into the registering account-ID of that session key index.
