Enum mycelium_kernel::drivers::pci::device::Id

pub enum Id {
    Known(&'static Device),
    Unknown(RawIds),
}

Represents a device’s vendor ID and [device ID].

Variants

Known(&'static Device)

A known ID.

This variant is returned if the device’s vendor ID and device ID exist in the PCI ID database, and information such as a string representing the name of the vendor or device can be returned.

Unknown(RawIds)

An unknown ID.

This variant is returned if the device’s vendor ID or device ID were not found in the PCI ID database.

This is not necessarily an error, as it may indicate that the database has not been updated to include a newer device, the device is a prototype that has not yet been registered with PCI-SIG, or the device is not a “real” device but an emulated device provided by a virtual machine. An unknown device may still be used, provided that its Class, Subclass, and prog IF provide sufficient information to program that device.

Implementations

impl Id

pub fn name(&self) -> Option<&'static str>

pub fn vendor(&self) -> Option<&'static Vendor>

pub fn device_id(&self) -> u16

pub fn vendor_id(&self) -> u16

Trait Implementations

impl Clone for Id

fn clone(&self) -> Id

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Id

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

Formats the value using the given formatter.

impl Display for Id

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

Formats the value using the given formatter.

impl PartialEq for Id

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

This method tests for self and other values to be equal, and is used by ==.

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

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