Enum TimePoint 

pub enum TimePoint {
    Seconds(f64),
    Spec(String),
}

A point in time: a bare JSON number of seconds, or a small string expression anchored to the beat grid.

Grammar (for the Spec string form)

An optional leading @ (forces the value onto the scenario’s absolute timeline — see the module doc), followed by one or more terms joined by + or -. Each term is <number><unit>, where unit is one of:

• s — seconds, taken as-is.
• ms — milliseconds, divided by 1000.
• b — beats: beat_offset + n * 60 / bpm (errors with TimeError::NoBpm when the scenario declares no bpm). A term’s sign multiplies this whole grid position, beat_offset included — so "@2.2s-1b" is “2.2s before wherever beat 1 lands,” not “1 raw beat length before 2.2s.”

Valid examples: "2.5s", "8b", "120ms", "8b+120ms", "@8b", "@2.2s-1b".

Variants

Seconds(f64)

A bare JSON number: seconds, always relative to whatever context resolves it (see TimePoint::resolve_relative).

Spec(String)

The string expression form — see the grammar above.
