Struct WeakDevice 

pub struct WeakDevice { /* private fields */ }

Weak reference to the device. Must be upgraded to strong reference before use. Upgrade will fail if last strong reference to device was dropped.

Implementations

impl WeakDevice

pub fn upgrade(&self) -> Option<Device>

Upgrades to strong reference.

pub fn is(&self, device: &Device) -> bool

Checks if this reference points to the same device.

Trait Implementations

impl Clone for WeakDevice

fn clone(&self) -> WeakDevice

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WeakDevice

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

Formats the value using the given formatter.

impl PartialEq<WeakDevice> for &Device

fn eq(&self, weak: &WeakDevice) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialEq<WeakDevice> for &WeakDevice

fn eq(&self, weak: &WeakDevice) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialEq<WeakDevice> for Device

fn eq(&self, weak: &WeakDevice) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialEq for WeakDevice

fn eq(&self, weak: &WeakDevice) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
