Struct DeviceSelector 

pub struct DeviceSelector { /* private fields */ }

A filter for matching devices in request_device.

Example

use nusb::{DeviceSelector, MaybeFuture};

let devices = nusb::request_device(&[
    DeviceSelector::all().with_vid_pid(0x1234, 0x5678),
    DeviceSelector::all().with_vid_pid(0x1111, 0x2222),
]).wait().unwrap();

Implementations

impl DeviceSelector

pub const fn all() -> DeviceSelector

A selector that matches all devices.

pub const fn with_vid(self, vendor_id: u16) -> DeviceSelector

Narrow the selector to only match devices with the given vendor ID.

pub const fn with_vid_pid( self, vendor_id: u16, product_id: u16, ) -> DeviceSelector

Narrow the selector to only match devices with the given vendor ID and product ID.

pub const fn with_class(self, class_code: u8) -> DeviceSelector

Narrow the selector to only match devices with the given class code.

pub const fn with_class_subclass( self, class_code: u8, subclass_code: u8, ) -> DeviceSelector

Narrow the selector to only match devices with the given class and subclass.

pub const fn with_class_subclass_protocol( self, class_code: u8, subclass_code: u8, protocol_code: u8, ) -> DeviceSelector

Narrow the selector to only match devices with the given class, subclass, and protocol.

pub fn with_serial_number(self, serial_number: String) -> DeviceSelector

Narrow the selector to only match devices with the given serial number.

pub fn vendor_id(&self) -> Option<u16>

Vendor ID, or None if not filtered by vendor ID.

pub fn product_id(&self) -> Option<u16>

Product ID, or None if not filtered by product ID.

pub fn class(&self) -> Option<u8>

Class code, or None if not filtered by class.

pub fn subclass(&self) -> Option<u8>

Subclass code, or None if not filtered by subclass.

pub fn protocol(&self) -> Option<u8>

Protocol code, or None if not filtered by protocol.

pub fn serial_number(&self) -> Option<&str>

Serial number, or None if not filtered by serial number.
