Struct mycelium_kernel::drivers::pci::Address

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

A PCI device address.

Implementations

impl Address

pub const fn new() -> Address

pub fn group(self) -> Option<NonZeroU16>

Returns the device’s segment group, if it is a PCI Express device.

PCI Express supports up to 65535 segment groups, each with 256 bus segments. Standard PCI does not support segment groups.

pub fn bus(self) -> u8

Returns the device’s bus segment.

PCI supports up to 256 bus segments.

pub fn device(self) -> u8

Returns the device number within its bus segment.

pub fn function(self) -> u8

Returns which function of the device this address refers to.

A device may support up to 8 separate functions.

pub fn with_group(self, group: Option<NonZeroU16>) -> Address

pub fn with_bus(self, bus: u8) -> Address

pub fn with_device(self, device: u8) -> Address

pub fn with_function(self, function: u8) -> Address

Trait Implementations

impl Clone for Address

fn clone(&self) -> Address

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Address

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

Formats the value using the given formatter.

impl Display for Address

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

Formats the value using the given formatter.

impl FromStr for Address

type Err = ParseError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Address, <Address as FromStr>::Err>

Parses a string s to return a value of this type.

impl LowerHex for Address

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

Formats the value using the given formatter.

impl Ord for Address

fn cmp(&self, other: &Address) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for Address

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

impl PartialOrd for Address

fn partial_cmp(&self, other: &Address) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl UpperHex for Address

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

Formats the value using the given formatter.
