Struct Bdf

pub struct Bdf(/* private fields */);

Unique identifier of a PCI device

BDF stands for bus, device, function, which is the standard way to identify and address individual PCI devices on a system.

Internally this is a newtype around a u32, with the BDF fields packed in such a way that the can be used to easily construct PCI configuration addresses.

Implementations

impl Bdf

pub const fn new(bus: u8, device: u8, function: u8) -> Self

Constructs a new BDF value from individual components.

The valid range for bus is 0..=255, for device is 0..=31, and for function is 0..=7. This function will silently truncate any extra leading bits from the device and function parameters before constructing the final BDF value.

pub const fn bus(&self) -> u8

Returns the bus number component of this BDF.

pub const fn device(&self) -> u8

Returns the device number component of this BDF.

pub const fn function(&self) -> u8

Returns the function number component of this BDF.

Trait Implementations

impl Clone for Bdf

fn clone(&self) -> Bdf

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Bdf

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

Formats the value using the given formatter.

impl Display for Bdf

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

Formats the value using the given formatter.

impl PartialEq for Bdf

fn eq(&self, other: &Bdf) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
