Struct AssignedBusRange 

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

Segment-local bus range assigned to a PCIe downstream port.

Stores a packed (secondary_bus, subordinate_bus) as an atomic u16, updated when the PCIe port’s bus numbers change. The segment number is not included here — it is a static property of the root complex and is held separately by the consumer (e.g., ITS wrappers).

Clone is cheap (just an Arc bump).

Implementations

impl AssignedBusRange

pub fn new() -> Self

Creates a new bus range initialized to zero.

pub fn set_bus_range(&self, secondary: u8, subordinate: u8)

Updates the bus range for the downstream port.

pub fn bus_range(&self) -> (u8, u8)

Returns the current (secondary_bus, subordinate_bus).

pub fn contains_bus(&self, bus: u8) -> bool

Returns whether bus falls within the current bus range (inclusive on both ends).

impl Default for AssignedBusRange

fn default() -> Self
