Methods

impl MidiMessage

pub fn try_from(slice: &[u8]) -> Result<Self, TryFromError>

Try create a MidiMessage from a slice of bytes.

This is pretty straight forward: Try to parse the data and create a MidiMessage object for it. Please note that this method does not support system-exclusive message due to their unorthodox nature. These are handled by the SystemExclusiveMessage struct.

The error cases are described in the TryFromError enum.
