Struct uefi::proto::device_path::DevicePath

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

Device path protocol.

A device path contains one or more device path instances made of up variable-length nodes. It ends with an END_ENTIRE node.

See the module-level documentation for more details.

Implementations

impl DevicePath

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

Create a DevicePath 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 const fn as_ffi_ptr(&self) -> *const FfiDevicePath

Cast to a FfiDevicePath pointer.

pub const fn instance_iter(&self) -> DevicePathInstanceIterator<'_>

Get an iterator over the DevicePathInstances in this path.

pub const fn node_iter(&self) -> DevicePathNodeIterator<'_>

Get an iterator over the DevicePathNodes starting at self. Iteration ends when a path is reached where is_end_entire is true. That ending path is not returned by the iterator.

Trait Implementations

impl Debug for DevicePath

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

Formats the value using the given formatter.

impl Identify for DevicePath

const GUID: Guid = _

Unique protocol identifier.

impl PartialEq<DevicePath> for DevicePath

fn eq(&self, other: &Self) -> 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 Pointee for DevicePathwhere [u8]: Pointee,

type Metadata = <[u8] as Pointee>::Metadata

The type for metadata in pointers and references to Self.

impl ProtocolPointer for DevicePath

unsafe fn ptr_from_ffi(ptr: *const c_void) -> *const Self

Create a const pointer to a Protocol from a c_void pointer.

unsafe fn mut_ptr_from_ffi(ptr: *mut c_void) -> *mut Self

Create a mutable pointer to a Protocol from a c_void pointer.
