Methods

impl<T: Clone> AccountsIndex<T>

pub fn scan_accounts<F>(&self, ancestors: &HashMap<Fork, usize>, func: F) where
    F: FnMut(&Pubkey, (&T, Fork)), 

call func with every pubkey and index visible from a given set of ancestors

pub fn get(
    &self,
    pubkey: &Pubkey,
    ancestors: &HashMap<Fork, usize>
) -> Option<(RwLockReadGuard<Vec<(Fork, T)>>, usize)>

Get an account The latest account that appears in ancestors or roots is returned.
