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