Struct helgoboss_midi::ControlChange14BitMessageScanner

pub struct ControlChange14BitMessageScanner { /* fields omitted */ }

Scanner for detecting 14-bit Control Change messages in a stream of short MIDI messages.

Example

use helgoboss_midi::test_util::control_change;
use helgoboss_midi::{
    Channel, ControlChange14BitMessage, ControlChange14BitMessageScanner, ControllerNumber, U14,
};

let mut scanner = ControlChange14BitMessageScanner::new();
let result_1 = scanner.feed(&control_change(5, 2, 8));
let result_2 = scanner.feed(&control_change(5, 34, 33));
assert_eq!(result_1, None);
assert_eq!(
    result_2,
    Some(ControlChange14BitMessage::new(
        Channel::new(5),
        ControllerNumber::new(2),
        U14::new(1057)
    ))
);

Implementations

impl ControlChange14BitMessageScanner

pub fn new() -> ControlChange14BitMessageScanner

Creates a new scanner.

pub fn feed(
    &mut self,
    msg: &impl ShortMessage
) -> Option<ControlChange14BitMessage>

Feeds the scanner a single short message.

Returns the 14-bit Control Change message if one has been detected.

pub fn reset(&mut self)

Resets the scanner discarding all intermediate scanning progress.
