Struct portmidi::InputPort

pub struct InputPort {
    // some fields omitted
}

Representation of an input midi port

Methods

impl InputPort

fn new(input_device: PortMidiDeviceId, buffer_size: i32) -> InputPort

Construct a new InputPort for input_device

fn open(&mut self) -> PortMidiResult<()>

Open the port returning an error if there is a problem

fn read(&mut self) -> PortMidiResult<Option<MidiEvent>>

Reads a single MidiEvent if one is avaible

A Result of None means no event was available.

See the PortMidi documentation for information on how it deals with input overflows

fn poll(&self) -> PortMidiResult<bool>

poll tests if there is input available, either returing a bool or an error

fn close(&mut self) -> PortMidiResult<()>

Closes the input, flushing any pending buffers

PortMidi attempts to close open streams when the application exits, but this can be difficult under Windows (according to the PortMidi documentation).
