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

A handle that might be either a DriverHandle or a ZirconHandle, depending on its bit pattern.

Implementations

impl MixedHandle

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

Makes a MixedHandle from an existing raw handle.

Safety

The handle must be valid and unowned, as this will take ownership of the handle and drop it when this object drops.

pub unsafe fn try_from_raw(handle: fdf_handle_t) -> Option<Self>

Makes a MixedHandle from an existing raw handle that might be zeroed (invalid).

Safety

The handle must be valid and unowned, as this will take ownership of the handle and drop it when this object drops.

pub fn from_zircon_handle(handle: ZirconHandle) -> Option<Self>

Makes a MixedHandle from an existing ZirconHandle. Returns None if the handle is invalid.

pub fn is_driver(&self) -> bool

Evaluates whether the contained handle is a driver handle or not

pub fn resolve(self) -> MixedHandleType<DriverHandle, ZirconHandle>

Resolves the handle to the appropriate real handle type

pub fn resolve_ref( &self, ) -> MixedHandleType<DriverHandleRef<'_>, ZirconHandleRef<'_>>

Resolves the handle to an appropriate real unowned handle type
