Implementations

impl DeviceType

pub const HARDWARE: DeviceType = _

Hardware Device Path.

This Device Path defines how a device is attached to the resource domain of a system, where resource domain is simply the shared memory, memory mapped I/ O, and I/O space of the system.

pub const ACPI: DeviceType = _

ACPI Device Path.

This Device Path is used to describe devices whose enumeration is not described in an industry-standard fashion. These devices must be described using ACPI AML in the ACPI namespace; this Device Path is a linkage to the ACPI namespace.

pub const MESSAGING: DeviceType = _

Messaging Device Path.

This Device Path is used to describe the connection of devices outside the resource domain of the system. This Device Path can describe physical messaging information such as a SCSI ID, or abstract information such as networking protocol IP addresses.

pub const MEDIA: DeviceType = _

Media Device Path.

This Device Path is used to describe the portion of a medium that is being abstracted by a boot service. For example, a Media Device Path could define which partition on a hard drive was being used.

pub const BIOS_BOOT_SPEC: DeviceType = _

BIOS Boot Specification Device Path.

This Device Path is used to point to boot legacy operating systems; it is based on the BIOS Boot Specification Version 1.01.

pub const END: DeviceType = _

End of Hardware Device Path.

Depending on the Sub-Type, this Device Path node is used to indicate the end of the Device Path instance or Device Path structure.

Trait Implementations

impl Clone for DeviceType

fn clone(&self) -> DeviceType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DeviceType

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

Formats the value using the given formatter.

impl Hash for DeviceType

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for DeviceType

fn cmp(&self, other: &DeviceType) -> 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,

Restrict a value to a certain interval.

impl PartialEq for DeviceType

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

impl PartialOrd for DeviceType

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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