High-level MIDI event types.

Marked #[non_exhaustive]: match with a wildcard arm, as new event kinds (e.g. SysEx) may be added in future versions without it being a breaking change.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Implementations

impl MidiEvent

pub fn from_midi_bytes(bytes: &[u8]) -> Option<MidiEvent>

Parse a single channel-voice MIDI message from raw bytes (status + data), as delivered by a MIDI input device.

Maps Note On/Off (a Note On with velocity 0 becomes a Note Off), Control Change, Pitch Bend (14-bit), channel/poly aftertouch, and Program Change. Returns None for empty/truncated input, running-status messages (no leading status byte), and system/realtime/SysEx messages.
