Struct midir::MidiOutput

pub struct MidiOutput { /* private fields */ }

An instance of MidiOutput is required for anything related to MIDI output. Create one with MidiOutput::new.

Implementations

impl MidiOutput

pub fn new(client_name: &str) -> Result<Self, InitError>

Creates a new MidiOutput object that is required for any MIDI output functionality.

pub fn ports(&self) -> MidiOutputPorts

Get a collection of all MIDI output ports that midir can connect to. The resulting vector contains one object per port, which you can use to query metadata about the port or connect to it in order to send MIDI messages.

pub fn port_count(&self) -> usize

Get the number of available MIDI output ports that midir can connect to.

pub fn port_name(&self, port: &MidiOutputPort) -> Result<String, PortInfoError>

Get the name of a specified MIDI output port.

An error will be returned when the port is no longer valid (e.g. the respective device has been disconnected).

pub fn connect( self, port: &MidiOutputPort, port_name: &str ) -> Result<MidiOutputConnection, ConnectError<MidiOutput>>

Connect to a specified MIDI output port in order to send messages. The connection will be kept open as long as the returned MidiOutputConnection is kept alive.

The port_name is an additional name that will be assigned to the connection. It is only used by some backends.

An error will be returned when the port is no longer valid (e.g. the respective device has been disconnected).

Trait Implementations

impl MidiIO for MidiOutput

type Port = MidiOutputPort

Type of an input or output port structure.

fn ports(&self) -> MidiOutputPorts

Get a collection of all MIDI input or output ports. The resulting vector contains one object per port, which you can use to query metadata about the port or connect to it.

fn port_count(&self) -> usize

Get the number of available MIDI input or output ports.

fn port_name(&self, port: &MidiOutputPort) -> Result<String, PortInfoError>

Get the name of a specified MIDI input or output port.

impl VirtualOutput for MidiOutput

fn create_virtual( self, port_name: &str ) -> Result<MidiOutputConnection, ConnectError<MidiOutput>>

Creates a virtual output port. Once it has been created, other applications can connect to this port and will receive MIDI messages that are sent to this port.
