Struct uefi::proto::device_path::DevicePathNode

#[repr(C, packed)]
pub struct DevicePathNode { /* private fields */ }

A single node within a DevicePath.

Each node starts with a DevicePathHeader. The rest of the data in the node depends on the type of node.

See the module-level documentation for more details.

Implementations

impl DevicePathNode

pub unsafe fn from_ffi_ptr<'a>(ptr: *const FfiDevicePath) -> &'a DevicePathNode

Create a DevicePathNode reference from an opaque pointer.

Safety

The input pointer must point to valid data. That data must remain valid for the lifetime 'a, and cannot be mutated during that lifetime.

pub fn as_ffi_ptr(&self) -> *const FfiDevicePath

Cast to a FfiDevicePath pointer.

pub fn device_type(&self) -> DeviceType

Type of device

pub fn sub_type(&self) -> DeviceSubType

Sub type of device

pub fn full_type(&self) -> (DeviceType, DeviceSubType)

Tuple of the node’s type and subtype.

pub fn length(&self) -> u16

Size (in bytes) of the full DevicePathNode, including the header.

pub fn is_end_entire(&self) -> bool

True if this node ends an entire DevicePath.

pub fn as_file_path_media_device_path(&self) -> Option<&FilePathMediaDevicePath>

Convert to a FilePathMediaDevicePath. Returns None if the node is not of the appropriate type.

Trait Implementations

impl Debug for DevicePathNode

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

Formats the value using the given formatter.

impl PartialEq<DevicePathNode> for DevicePathNode

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