Enum Unit 

#[non_exhaustive]
pub enum Unit {
    Minutes,
    Days,
}

What a Track’s integers count.

Track::fraction never needed this – the arithmetic is the same whatever the numbers mean – which is exactly how the ruler came to assume minutes and print 00:00 over a month. A renderer drawing an axis has to write a label, and it cannot derive the unit from the numbers.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Minutes

Minutes from the start of a day. A day view.

Days

Whole days. A month strip, a sprint, a stretch of leave.

A day-granularity axis is a strip, not a calendar: one line with spans laid along it. What it deliberately does not do is wrap into weeks, which is the shape that makes weekday periodicity visible and the one job of a month grid that a strip cannot take over. See the crate header.
