Enum Relation 

pub enum Relation {
    Before,
    At,
    After,
    Uncertain(Uncertainty),
}

UTC-qualified relation of a source label to the caller’s lossless reading. This is a temporal fact, not a rule for application acceptance.

Variants

Before

Source label is strictly before the reading.

At

Source label equals the exact reading.

After

Source label is strictly after the reading.

Uncertain(Uncertainty)

Supplied UTC facts cannot establish an input label.
