Trait rsynth::meta::Port[−][src]

pub trait Port<T> {
    type PortData;
    fn in_ports(&self) -> &[Self::PortData];
    fn out_ports(&self) -> &[Self::PortData];
}

Define meta-data for input ports and output ports.

The type parameter T is a dummy type parameter so that meta-data for different types of ports can be defined. Typical values for T are MidiPort and AudioPort.

Example

use rsynth::meta::{Port, MidiPort, AudioPort};
struct MyMetaData {
    audio_input_port_names: Vec<String>,
    audio_output_port_names: Vec<String>,
    midi_input_port_names: Vec<String>,
    midi_output_port_names: Vec<String>,
}

impl Port<AudioPort> for MyMetaData {
    type PortData = String;
    fn in_ports(&self) -> &[Self::PortData] {
        self.audio_input_port_names.as_slice()
    }
    fn out_ports(&self) -> &[Self::PortData] {
        self.audio_output_port_names.as_slice()
    }
}

impl Port<MidiPort> for MyMetaData {
    type PortData = String;
    fn in_ports(&self) -> &[Self::PortData] {
        self.audio_input_port_names.as_slice()
    }
    fn out_ports(&self) -> &[Self::PortData] {
        self.audio_output_port_names.as_slice()
    }
}
