Trait Implementations

impl<'a> AsPciSubregion<'a> for NullExtendedCapability<'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.

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

Performs copy-assignment from source. Read more

impl Debug for NullExtendedCapability<'_>

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

impl<'a> ExtendedCapability<'a> for NullExtendedCapability<'a>

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