Enum netstack3_base::EitherDeviceId

pub enum EitherDeviceId<S, W> {
    Strong(S),
    Weak(W),
}

A device id that might be either in its strong or weak form.

Variants

Weak(W)

Implementations

impl<S: StrongDeviceIdentifier, W: WeakDeviceIdentifier<Strong = S>> EitherDeviceId<&S, &W>

pub fn as_strong_ref<'a>(&'a self) -> Option<Cow<'a, S>>

Returns a Cow reference for the strong variant.

Attempts to upgrade if this is a Weak variant.

impl<S, W> EitherDeviceId<S, W>

pub fn as_ref<'a, S2, W2>(&'a self) -> EitherDeviceId<&'a S2, &'a W2>

where S: Borrow<S2>, W: Borrow<W2>,

Returns a borrowed version of this EitherDeviceId.

impl<S: StrongDeviceIdentifier<Weak = W>, W: WeakDeviceIdentifier<Strong = S>> EitherDeviceId<S, W>

pub fn as_strong<'a>(&'a self) -> Option<Cow<'a, S>>

Returns a Cow reference for the Strong variant.

Attempts to upgrade if this is a Weak variant.

pub fn as_weak<'a>(&'a self) -> Cow<'a, W>

Returns a Cow reference for the Weak variant.

Downgrades if this is a Strong variant.

Trait Implementations

impl<S: Clone, W: Clone> Clone for EitherDeviceId<S, W>

fn clone(&self) -> EitherDeviceId<S, W>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<S: PartialEq, W: PartialEq + PartialEq<S>> PartialEq for EitherDeviceId<S, W>

fn eq(&self, other: &EitherDeviceId<S, W>) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

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