Enum mycelium_kernel::drivers::pci::device::BaseAddress

pub enum BaseAddress {

A PCI Base Address Register (BAR).

Base Address Registers (or BARs) can be used to hold memory addresses used by the device, or offsets for port addresses. Typically, memory address BARs need to be located in physical RAM, while I/O space BARs can reside at any memory address (even beyond physical memory).

Trait Implementations

impl Clone for BaseAddress

fn clone(&self) -> BaseAddress

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for BaseAddress

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

Formats the value using the given formatter.

impl PartialEq for BaseAddress

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