Struct PointStamp

pub struct PointStamp<T> {
    pub vector: Vec<T>,
}

A sequence of timestamps, partially ordered by the product order.

Sequences of different lengths are compared as if extended indefinitely by T::minimum(). Sequences are not guaranteed to be “minimal”, and may end with T::minimum() entries.

Fields

vector: Vec<T>

A sequence of timestamps corresponding to timestamps in a sequence of nested scopes.

Implementations

impl<T> PointStamp<T>

pub fn new(vector: Vec<T>) -> Self
