Trait Implementations

source

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

source

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

Returns a PciSubregion corresponding to self.

source

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

Returns a PciSubregion corresponding to a range of self.

source

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

source

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). Read more

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