Midi parsing library for Rust

WMIDI

Midi encoding and decoding library suitable for real-time execution.

Usage

use std::convert::TryFrom;

// Decoding messages from bytes.
fn handle_midi_message(bytes: &[u8]) -> Result<(), wmidi::FromBytesError> {
    let message = wmidi::MidiMessage::try_from(bytes)?;
    if let wmidi::MidiMessage::NoteOn(_, note, _) = message {
        println!("Singing {}", note);
    }
    Ok(())
}

// Encoding messages to bytes.
fn midi_to_bytes(message: wmidi::MidiMessage<'_>) -> Vec<u8> {
    let mut bytes = vec![0u8; message.bytes_size()];
    message.copy_to_slice(bytes.as_mut_slice()).unwrap();
    bytes
}

Changelog

3.1

• Rename MidiMessage::wire_size() to MidiMessage::bytes_size().
• Introduce MidiMessage::copy_to_slice() method.

3.0

• Instances of U7 and U14 now have bounds checking.
• Note is now an enum instead of a u8. Can be converted with Note::try_from and u8::from.
