Struct JackMidiEvent 

pub struct JackMidiEvent { /* private fields */ }

Short MIDI event delivered by JACK for a process block.

Implementations

impl JackMidiEvent

pub fn short(offset: u32, bytes: &[u8]) -> Result<Self>

Builds a short MIDI event delivered at sample offset within the block.

bytes carries one to three status/data bytes; shorter messages are zero-padded to the fixed three-byte buffer.

Errors

Returns an error when bytes is empty or longer than three bytes.

Examples

use sim_lib_stream_jack::JackMidiEvent;

let note_on = JackMidiEvent::short(64, &[0x90, 60, 100]).unwrap();
assert_eq!(note_on.offset(), 64);
assert_eq!(note_on.byte_len(), 3);
assert_eq!(note_on.bytes(), [0x90, 60, 100]);

let too_long = JackMidiEvent::short(0, &[0, 1, 2, 3]);
assert!(too_long.is_err());

pub fn offset(self) -> u32

Returns the event’s sample offset within its process block.

pub fn bytes(self) -> [u8; 3]

Returns the three-byte message buffer, zero-padded past byte_len.

pub fn byte_len(self) -> u8

Returns the number of meaningful bytes in the message (one to three).

Trait Implementations

impl Clone for JackMidiEvent

fn clone(&self) -> JackMidiEvent

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for JackMidiEvent

impl Debug for JackMidiEvent

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for JackMidiEvent

impl PartialEq for JackMidiEvent

fn eq(&self, other: &JackMidiEvent) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
