Struct mumuse::music::stream::Stream

pub struct Stream {
    pub events: Vec<Event>,
}

Temporal arrangement of events

Fields

events: Vec<Event>

Implementations

impl Stream

pub fn new() -> Self

Creates a new empty Stream with no events.

Examples

Basic usage:

use mumuse::music::stream::Stream;
let s = Stream::new(); 

pub fn add_event(&mut self, event: Event)

Adds event to stream

Examples

Basic usage:

use mumuse::music::{time::Time, note::Note, stream::{Stream, Event}};
use mumuse::messages::Status;
let mut stream: Stream = Stream::new();
let time: Time = Time::new(1, 16, 1);
let note: Note = Note::try_from("A3").unwrap();
stream.add_event(Event::new(time, Status::NoteOn, note));

pub fn add_note(&mut self, note: Note, time: Time, duration: Duration)

Adds note to stream

Examples

Basic usage:

use mumuse::music::{time::Time, note::Note, stream::Stream, duration::Duration};
let mut stream: Stream = Stream::new();
let note: Note = Note::try_from("A3").unwrap();
let time: Time = Time::new(1, 16, 1);
let duration: Duration = Duration::new(16, 1);
stream.add_note(note, time, duration);

pub fn to_seconds(&self, bpm: f64, bpb: u32) -> Vec<(f64, Status, Note)>

Converts Events to seconds timeline

In order to convert the stream with Time events, one need to declare a bpm (beats per minutes) and a bpb (beats per bar).

Examples

Basic usage:

use mumuse::music::{time::Time, note::Note, stream::Stream, duration::Duration};
let mut stream: Stream = Stream::new();
let note: Note = Note::try_from("A3").unwrap();
let time: Time = Time::new(1, 16, 1);
let duration: Duration = Duration::new(16, 1);
stream.add_note(note, time, duration);
let stream_seconds = stream.to_seconds(120.0, 4);

pub fn play(&self, conn_out: &mut MidiOutputConnection, bpm: f64, bpb: u32)

Plays stream of events in real time

Use ticking for playing the stream of events at regular intervals. For each tick, the events with Time to seconds lying in the tick window are sent as MIDI. The bpm (beats per minutes) and bpb (beats per bar) are needed for the conversion to seconds.

Trait Implementations

impl Default for Stream

fn default() -> Stream

Returns the “default value” for a type.
