Trait Implementations

impl<'a> AsPciSubregion<'a> for NullCapability<'a>

fn as_subregion(&self) -> PciSubregion<'a>

Returns a PciSubregion corresponding to self.

fn subregion(&self, range: impl RangeBounds<u64>) -> PciSubregion<'a>

Returns a PciSubregion corresponding to a range of self.

impl<'a> Capability<'a> for NullCapability<'a>

fn backed_by(as_subregion: impl AsPciSubregion<'a>) -> Result<Option<Self>>

Tries to create an instance of this Capability backed by the given AsPciSubregion. If things like for instance the Capablity ID and possibly other factors don’t match what is expected for the present type, returns Ok(None).

fn header(&self) -> CapabilityHeader<'a>

The spec doesn’t really define a header part explicitly, but this holds the two fields that are common to all Capabilities.

impl<'a> Clone for NullCapability<'a>

fn clone(&self) -> NullCapability<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NullCapability<'_>

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

Formats the value using the given formatter.
