Required methods

fn graph_mut(channel: &mut Self::Channel) -> &mut Self::Graph[src]

fn touch_channel(&mut self, channel: &mut Self::Channel, t: Option<u64>)[src]

fn put_changes(
    &mut self,
    channel: &mut Self::Channel,
    p: ChangeId,
    t: ApplyTimestamp,
    h: &Hash
) -> Result<Option<Merkle>, TxnErr<Self::GraphError>>[src]

Add a change and a timestamp to a change table. Returns None if and only if (p, t) was already in the change table, in which case no insertion happened. Returns the new state else.

fn del_changes(
    &mut self,
    channel: &mut Self::Channel,
    p: ChangeId,
    t: ApplyTimestamp
) -> Result<bool, TxnErr<Self::GraphError>>[src]

Delete a change from a change table. Returns true if and only if (p, t) was in the change table.
