source · [−]

pub struct FrontierReconcile<T> {
    frontiers: HashMap<GlobalId, FrontierState<T>>,

Expand description

Reconciles a set of frontiers that are each associated with a GlobalId.

Fields

frontiers: HashMap<GlobalId, FrontierState<T>>epoch: u64

Implementations

source

impl<T> FrontierReconcile<T> where
T: Timestamp + Copy,

source

pub fn bump_epoch(&mut self)

Bumps the internal epoch to account for a new controller.

After calling this method, absorb will no longer return any changes. FrontierReconcile::start_tracking must be called again for any frontiers that remain of interest.

source

pub fn start_tracking(&mut self, id: GlobalId) -> ChangeBatch<T>

Starts tracking the frontier for an ID.

If the ID is already tracked, returns a change batch that describes how to update the minimum frontier to the currently tracked frontier.

source

pub fn stop_tracking(&mut self, id: GlobalId) -> Option<MutableAntichain<T>>

Stops tracking the frontier for an ID.

Returns the tracked frontier for the ID, if the ID was tracked.

source

pub fn is_tracked(&self, id: GlobalId) -> bool

Reports whether the ID is currently tracked.

source

pub fn absorb(&mut self, frontiers: &mut Vec<(GlobalId, ChangeBatch<T>)>)

Absorbs new frontiers and mutates the provided frontiers to reflect the tracked state.

source

pub fn clear(&mut self)

Removes all tracked frontiers.
