pub fn decode_channel(
status: u8,
data: &[u8],
) -> Result<ChannelMessage, MidiError>Expand description
Decode a channel message from its (status, data) wire bytes: the inverse
of encode_channel.
The channel is taken from the low nibble of status and the message type
from the high nibble. Each consumed data byte must be a valid 7-bit value
(MidiError::InvalidU7); a status whose high nibble is not a channel-voice
type yields MidiError::NotChannelStatus, and a data slice shorter than
the message requires yields MidiError::TruncatedChannel. Pitch-bend’s
two 7-bit data bytes are recombined into the 14-bit value.
