pub struct TimeStamp {
    pub(crate) clock: u64,
}
Expand description

The “time stamp” is a simple clock that gets incremented each time we encounter a positive answer in processing a particular strand. This is used as an optimization to help us figure out when we may have changed inference variables.

Fields

clock: u64
