Struct RecordStatus

pub struct RecordStatus {
    pub hosts: HashMap<HostId, HashMap<String, RecordIdx>>,
}

An index representing the current state of the record stores This can be both remote, or local, and compared in either direction

Fields

hosts: HashMap<HostId, HashMap<String, RecordIdx>>

Implementations

impl RecordStatus

pub fn new() -> RecordStatus

pub fn set(&mut self, tail: Record<DecryptedData>)

Insert a new tail record into the store

pub fn set_raw(&mut self, host: HostId, tag: String, tail_id: RecordIdx)

pub fn get(&self, host: HostId, tag: String) -> Option<RecordIdx>

pub fn diff(&self, other: &Self) -> Vec<Diff>

Diff this index with another, likely remote index. The two diffs can then be reconciled, and the optimal change set calculated Returns a tuple, with (host, tag, Option(OTHER)) OTHER is set to the value of the idx on the other machine. If it is greater than our index, then we need to do some downloading. If it is smaller, then we need to do some uploading Note that we cannot upload if we are not the owner of the record store - hosts can only write to their own store.
