Struct differential_dataflow::trace::description::Description
[−]
[src]
pub struct Description<Time> { /* fields omitted */ }
Describes an interval of partially ordered times.
A Description
indicates a set of partially ordered times, and a moment at which they are
observed. The lower
and upper
frontiers bound the times contained within, and the since
frontier indicates a moment at which the times were observed. If since
is strictly in
advance of lower
, the contained times may be "advanced" to times which appear equivalent to
any time after since
.
Methods
impl<Time: Clone> Description<Time>
[src]
pub fn new(lower: &[Time], upper: &[Time], since: &[Time]) -> Self
[src]
Returns a new description from its component parts.
impl<Time> Description<Time>
[src]
pub fn lower(&self) -> &[Time]
[src]
The lower envelope for times in the interval.
pub fn upper(&self) -> &[Time]
[src]
The upper envelope for times in the interval.
pub fn since(&self) -> &[Time]
[src]
Times from whose future the interval may be observed.
