WMIDI

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

Usage

```rust use std::convert::TryFrom;

// Decoding messages from bytes. fn handlemidimessage(bytes: &[u8]) -> Result<(), wmidi::FromBytesError> { let message = wmidi::MidiMessage::tryfrom(bytes)?; if let wmidi::MidiMessage::NoteOn(, note, val) = message { let volume = u8::from(val) as u8 / 127.0; println!("Singing {} at volume {}", note, volume); } Ok(()) }

// Encoding messages to bytes. fn miditobytes(message: wmidi::MidiMessage<'>) -> Vec { let mut bytes = vec![0u8; message.bytessize()]; message.copytoslice(bytes.asmutslice()).unwrap(); bytes } ```

Testing & Benchmarking

• Build with cargo build.
• Test with cargo test.
• Benchmark with cargo bench. The results will be under ./target/criterion/report/index.html.

Changelog

4.0.0

• New ControlFunction type which simply wraps a U7.
• Constants and documentation for all ControlFunction values.
• Renumber Note enums/consts to be more consistent with midi; for example, C0 is now C1.

3.1.0

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

3.0.0

• 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.
