}

A generic PCI configuration space capability structure.

Required Methods

fn label(&self) -> &str

A descriptive label for use in Save/Restore + Inspect output

fn capability_id(&self) -> CapabilityId

Returns the PCI capability ID for this capability

fn len(&self) -> usize

Length of the capability structure

fn read(&self, offset: u16, value: ByteEnabledDwordRead<'_>)

Read a byte-enabled DWORD at the given capability-relative offset. The offset must be 32-bit aligned.

fn write(&mut self, offset: u16, val: ByteEnabledDwordWrite)

Write a byte-enabled DWORD to the given capability-relative offset. The offset must be 32-bit aligned.

fn reset(&mut self)

Reset the capability

Provided Methods

fn as_pci_express(&self) -> Option<&PciExpressCapability>

Downcast to PCI Express capability

fn as_pci_express_mut(&mut self) -> Option<&mut PciExpressCapability>

Downcast to PCI Express capability (mutable)

fn as_msi_cap(&self) -> Option<&MsiCapability>

Downcast to MSI capability

fn as_msi_cap_mut(&mut self) -> Option<&mut MsiCapability>

Downcast to MSI capability (mutable)
