Struct CapabilityHeader

pub struct CapabilityHeader<'a> { /* private fields */ }

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

Implementations

impl<'a> CapabilityHeader<'a>

pub fn capability_id(&self) -> PciRegisterRo<'a, u8>

pub fn next_capability_pointer(&self) -> PciRegisterRo<'a, u8>

This field contains the offset to the next PCI Capability structure or 0x00 if no other items exist in the linked list of Capabilities.

You don’t need to be using this directly. Use PciCapabilities to iterate over capabilities instead.

Trait Implementations

impl<'a> AsPciSubregion<'a> for CapabilityHeader<'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> BackedByPciSubregion<'a> for CapabilityHeader<'a>

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

Does not check whether the subregion is big enough. If it isn’t, accesses may later fail.

impl<'a> Clone for CapabilityHeader<'a>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CapabilityHeader<'_>

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

Formats the value using the given formatter.

impl<'a> Copy for CapabilityHeader<'a>
