Struct PciAddress 

pub struct PciAddress {
    pub segment: u16,
    pub bus: u8,
    pub device: u8,
    pub function: u8,
}

PCI device address components

Fields

segment: u16

PCI segment/domain (usually 0)

bus: u8

Bus number (0-255)

device: u8

Device number (0-31)

function: u8

Function number (0-7)

Implementations

impl PciAddress

pub const fn new(segment: u16, bus: u8, device: u8, function: u8) -> Self

Create a new PCI address

pub const fn ecam_offset(&self) -> usize

Calculate ECAM offset for this address

ECAM uses a flat memory mapping where each function gets 4KB: offset = (bus << 20) | (device << 15) | (function << 12)

Trait Implementations

impl Clone for PciAddress

fn clone(&self) -> PciAddress

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PciAddress

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

Formats the value using the given formatter.

impl PartialEq for PciAddress

fn eq(&self, other: &PciAddress) -> 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.
