Struct AcsExtendedCapability 

pub struct AcsExtendedCapability { /* private fields */ }

PCIe Access Control Services (ACS) extended capability emulator.

Implementations

impl AcsExtendedCapability

pub fn new() -> Self

Creates an ACS capability with the default set of sub-capabilities enabled (SV, TB, RR, CR, UF, DT).

pub fn with_capabilities(capability_bits: u16) -> Self

Creates an ACS capability with the sub-capabilities indicated by capability_bits.

Trait Implementations

impl Debug for AcsExtendedCapability

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

Formats the value using the given formatter.

impl Inspect for AcsExtendedCapability

fn inspect(&self, req: Request<'_>)

impl PciExtendedCapability for AcsExtendedCapability

fn label(&self) -> &str

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

fn extended_capability_id(&self) -> u16

Returns the PCIe extended capability ID for this capability.

fn capability_version(&self) -> u8
