Struct PortLayout 

pub struct PortLayout {
    pub num_audio_in: u32,
    pub num_audio_out: u32,
    pub num_params: u32,
    pub num_meters: u32,
    pub accepts_midi_in: bool,
    pub has_midi_out: bool,
}

Describes where each logical port sits in the flat LV2 port-index space. Filled in once at instantiate() time.

Fields

num_audio_in: u32

num_audio_out: u32

num_params: u32

num_meters: u32

accepts_midi_in: bool

Whether the input atom port should additionally advertise midi:MidiEvent support. The port itself always exists - hosts deliver time:Position through it regardless of whether the plugin consumes MIDI.

has_midi_out: bool

Implementations

impl PortLayout

pub fn audio_in_start(&self) -> u32

pub fn audio_out_start(&self) -> u32

pub fn control_start(&self) -> u32

pub fn meter_start(&self) -> u32

pub fn atom_in_port(&self) -> u32

Index of the DSP input atom port. Always present: carries time:Position (transport) for every plugin type and additionally midi:MidiEvent for instruments / note effects.

pub fn midi_out_port(&self) -> Option<u32>

pub fn notify_out_port(&self) -> u32

Index of the DSP→UI notification atom port. Always present: the DSP writes host transport (and any future plugin-defined notify messages) here, and the UI listens via ui:portNotification.

pub fn total(&self) -> u32

Trait Implementations

impl Clone for PortLayout

fn clone(&self) -> PortLayout

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PortLayout

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

Formats the value using the given formatter.
