Enum TimeExpression 

#[non_exhaustive]
pub enum TimeExpression {
    ClockTime {
        hours: u32,
        minutes: u8,
        seconds: u8,
        fraction: Option<String>,
        frames: Option<u32>,
        sub_frames: Option<u32>,
    },
    OffsetTime {
        count: u64,
        fraction: Option<String>,
        metric: TimeMetric,
    },
    WallclockTime {
        form: WallclockForm,
    },
}

A parsed time expression.

While the grammar in §12.3.1 defines three forms (clock-time, offset-time, wallclock-time), we represent all parsed time expressions uniformly.

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.

ClockTime

Clock-time: HH:MM:SS[.fraction][:frames[.sub-frames]]

Fields

hours: u32

Hours (unbounded — can be ≥ 100).

minutes: u8

Minutes [0, 59].

seconds: u8

Seconds [0, 60] (60 = leap second).

fraction: Option<String>

Fractional seconds, as a string of digits after the decimal point.

frames: Option<u32>

Frames component (HH:MM:SS:FF).

sub_frames: Option<u32>

Sub-frames component (HH:MM:SS:FF.SF).

OffsetTime

Offset-time: count[.fraction]metric

Fields

count: u64

The integer count part.

fraction: Option<String>

Fractional part, as a string of digits.

metric: TimeMetric

The metric unit.

WallclockTime

Wallclock-time: wallclock(date-time|wall-time|date)

Fields

form: WallclockForm

The wallclock form: date-time, wall-time, or date.
