[−][src]Struct differential_dataflow::trace::wrappers::rc::TraceBox

pub struct TraceBox<Tr> where
    Tr::Time: Lattice + Ord + Clone + 'static,
    Tr: TraceReader,  {
    pub advance_frontiers: MutableAntichain<Tr::Time>,
    pub through_frontiers: MutableAntichain<Tr::Time>,
    pub trace: Tr,
}

A wrapper around a trace which tracks the frontiers of all referees.

This is an internal type, unlikely to be useful to higher-level programs, but exposed just in case. This type is equivalent to a RefCell, in that it wraps the mutable state that multiple referrers may influence.

Fields

advance_frontiers: MutableAntichain<Tr::Time>

accumulated holds on times for advancement.

through_frontiers: MutableAntichain<Tr::Time>

accumulated holds on times for distinction.

trace: Tr

The wrapped trace.

Methods

impl<Tr> TraceBox<Tr> where
    Tr::Time: Lattice + Ord + Clone + 'static,
    Tr: TraceReader, [src]

pub fn new(trace: Tr) -> Self[src]

Moves an existing trace into a shareable trace wrapper.

The trace may already exist and have non-initial advance and distinguish frontiers. The boxing process will fish these out and make sure that they are used for the initial read capabilities.

pub fn adjust_advance_frontier(
    &mut self,
    lower: &[Tr::Time],
    upper: &[Tr::Time]
)[src]

Replaces elements of lower with those of upper.

pub fn adjust_through_frontier(
    &mut self,
    lower: &[Tr::Time],
    upper: &[Tr::Time]
)[src]

Replaces elements of lower with those of upper.
