Macro command_writers_and_readers

macro_rules! command_writers_and_readers {
    ($($field_name:ident: $type:ty),*$(,)?) => { ... };
}

Available on crate feature dep_kira only.

Creates a set of command writers and readers and a constructor for them. You’ll only need to use this if you’re making your own implementation of Sound, Effect, or Modulator.

Example

This macro call…

command_writers_and_readers! {
	set_phase: f64,
	set_frequency: ValueChangeCommand<f64>,
}

…will produce this code:

pub(crate) struct CommandWriters {
	set_phase: kira::command::CommandWriter<f64>,
	set_frequency: kira::command::CommandWriter<ValueChangeCommand<f64>>,
}

pub(crate) struct CommandReaders {
	set_phase: kira::command::CommandReader<f64>,
	set_frequency: kira::command::CommandReader<ValueChangeCommand<f64>>,
}

#[must_use]
pub(crate) fn command_writers_and_readers() -> (CommandWriters, CommandReaders) {
	let (set_phase_writer, set_phase_reader) = kira::command::command_writer_and_reader();
	let (set_frequency_writer, set_frequency_reader) = kira::command::command_writer_and_reader();
	let command_writers = CommandWriters {
		set_phase: set_phase_writer,
		set_frequency: set_frequency_writer,
	};
	let command_readers = CommandReaders {
		set_phase: set_phase_reader,
		set_frequency: set_frequency_reader,
	};
	(command_writers, command_readers)
}
