Struct fdf::DriverHandle

#[repr(C)]
pub struct DriverHandle(/* private fields */);

A handle representing some resource managed by the driver runtime.

Implementations

impl DriverHandle

pub unsafe fn new_unchecked(handle: NonZero<fdf_handle_t>) -> Self

Constructs a DriverHandle for the given fdf_handle_t

Safety

The caller is responsible for ensuring that the handle given is a valid driver handle:

• It has the marker bits set correctly
• It is not “owned” elsewhere

pub fn as_handle_ref(&self) -> DriverHandleRef<'_>

Gets a DriverHandleRef of this handle

pub unsafe fn get_raw(&self) -> NonZero<fdf_handle_t>

Gets the raw handle object

Safety

The caller must be sure to not let this handle outlive the lifetime of the object it came from.

pub fn into_raw(self) -> NonZero<fdf_handle_t>

Turns this handle into its raw handle number, without dropping the handle. The caller is responsible for ensuring that the handle is released or reconstituted into a DriverHandle.

Trait Implementations

impl Debug for DriverHandle

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

Formats the value using the given formatter.

impl Drop for DriverHandle

fn drop(&mut self)

Executes the destructor for this type.

impl From<DriverHandle> for MixedHandle

fn from(value: DriverHandle) -> Self

Converts to this type from the input type.

impl Hash for DriverHandle

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 DriverHandle

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

fn eq(&self, other: &DriverHandle) -> 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 DriverHandle

fn partial_cmp(&self, other: &DriverHandle) -> 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.
