Enum SceneStart 

pub enum SceneStart {
    Auto(SceneStartAuto),
    At(TimePoint),
}

When a scene starts, on the scenario’s absolute timeline. See Scene::at.

Not #[derive(Deserialize)] (see [SceneStartDe] / its manual Deserialize impl just below): a syntactically malformed at — "at": "banana" — must be rejected the moment the scenario is deserialized, not discovered later as a silent fallback to automatic placement. A derive can’t express that extra grammar check, only the untagged try-"auto"-then-TimePoint shape.

Variants

Auto(SceneStartAuto)

Immediately after the previous scene’s own window ends. Serializes and deserializes as the bare string "auto".

At(TimePoint)

An explicit point on the scenario’s absolute timeline. Grammar is validated at deserialize time via TimePoint::validate_grammar — resolving it (which additionally needs bpm for a beat unit) is a separate, later step: rustmotion validate’s schema pass, which can name the offending scene and report unresolved_beat_unit — see crates/rustmotion/src/cli/commands/validate_schema.rs.
