44/// Crate-wide error. Each element defines its own `{Element}Error` (see
45/// [`FileDemuxError`], [`SwDecoderError`], [`QueueError`]) for its own
46/// domain-specific failures; this enum just aggregates them so trait
47/// methods (`Sink::consume`, `SourceElement::run`, ...) — which have to
48/// return one common error type to stay object-safe across arbitrary
49/// `Box<dyn Sink>` — can report any of them. `?` chains through
50/// automatically: an element's own function returns its own error type,
51/// and the moment that gets used with `?` inside a function returning
52/// this top-level `Result`, it's converted here via `#[from]`.
