Struct DeviceList 

pub struct DeviceList<T>
where
    T: UsbContext,
{ /* private fields */ }

A list of detected USB devices.

Implementations

impl DeviceList<GlobalContext>

pub fn new() -> Result<DeviceList<GlobalContext>, Error>

impl<T> DeviceList<T>

where T: UsbContext,

pub fn new_with_context(context: T) -> Result<DeviceList<T>, Error>

pub fn len(&self) -> usize

Returns the number of devices in the list.

pub fn is_empty(&self) -> bool

Returns true if the list is empty, else returns false.

pub fn iter(&self) -> Devices<'_, T>

Returns an iterator over the devices in the list.

The iterator yields a sequence of Device objects.

Trait Implementations

impl<T> Drop for DeviceList<T>

where T: UsbContext,

fn drop(&mut self)

Frees the device list.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
