Struct UnsupportedChannelCount 

pub struct UnsupportedChannelCount { /* private fields */ }

Payload for ConvertError::UnsupportedChannelCount.

A channel count this crate will not carry: more than u8::MAX, which the portable AudioFrame seat cannot hold, or none at all on a frame that claims samples.

Refused, never clamped. Clamping to 255 was silent truncation of exactly the kind this boundary exists to refuse: a 256-channel packed frame then computed its byte product from the clipped count and copied 510 of its 512 bytes, delivering a short buffer that advertised 255 channels. A short read is not a smaller frame; it is a wrong one.

The count is carried signed, as AVChannelLayout.nb_channels declares it. It has to be: a negative count is one of the things this arm refuses, and the first version of this refusal read the count off a materialised layout description that had already floored it to zero — so nb_channels == -1 arrived looking like a legitimate zero-channel frame and was never seen by the guard meant to catch it.
