Struct BusDeviceFunction

pub struct BusDeviceFunction {
    pub bus: u8,
    pub device: u8,
    pub function: u8,
}

An identifier for a PCI bus, device and function. PCI设备的唯一标识

Fields

bus: u8

The PCI bus number, between 0 and 255.

device: u8

The device number on the bus, between 0 and 31.

function: u8

The function number of the device, between 0 and 7.

Implementations

impl BusDeviceFunction

pub fn valid(&self) -> bool

Returns whether the device and function numbers are valid, i.e. the device is between 0 and @brief 检测BusDeviceFunction实例是否有效 @param self @return bool 是否有效

Trait Implementations

impl Clone for BusDeviceFunction

fn clone(&self) -> BusDeviceFunction

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for BusDeviceFunction

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

Formats the value using the given formatter.

impl Display for BusDeviceFunction

实现BusDeviceFunction的Display trait，使其可以直接输出

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

Formats the value using the given formatter.

impl PartialEq for BusDeviceFunction

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