Enum Rounding 

#[non_exhaustive]
pub enum Rounding {
    NearestAway,
    Floor,
    Ceil,
    TowardZero,
}

How a rescale operation rounds a result that falls between two integer ticks of the target base.

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.

NearestAway

Round to the nearest tick; a tie (exactly halfway) rounds away from zero (+1.5 → +2, -1.5 → -2). The default, and the mode the plain rescale uses.

Floor

Round toward negative infinity. The right choice for DTS-like stamps that must never land after the true instant.

Ceil

Round toward positive infinity. The mirror of Rounding::Floor for end-of-range stamps that must never land before the true instant.

TowardZero

Round toward zero (truncate the fractional part).
