Trait SnapshotSource 

pub trait SnapshotSource {
    // Required method
    fn get(
        &self,
        key: &Rc<LedgerKey>,
    ) -> Result<Option<EntryWithLiveUntil>, HostError>;
}

A helper type used by [FootprintMode::Recording] to provide access to a stable read-snapshot of a ledger. The snapshot is expected to have access to all the persistent entries, including the archived entries. It also is allowed (but doesn’t have to) to return expired temporary entries.

Required Methods

fn get( &self, key: &Rc<LedgerKey>, ) -> Result<Option<EntryWithLiveUntil>, HostError>

Returns the ledger entry for the key and its live_until ledger if entry exists, or None otherwise.
