Union WireOptionalDriverChannel

#[repr(C, align(4))]
pub union WireOptionalDriverChannel {
    /* private fields */
}

The FIDL wire type for optional DriverChannels.

This type follows the FIDL wire format for handles, and is separate from the Zircon handle optional wire type. This ensures that we never confuse the two types when using FIDL.

Implementations

impl WireOptionalDriverChannel

pub fn set_encoded_present(out: &mut MaybeUninit<Self>)

Encodes a driver handle as present in a slot.

pub fn set_encoded_absent(out: &mut MaybeUninit<Self>)

Encodes a driver handle as absent in an output.

pub fn is_some(&self) -> bool

Returns whether a handle is present.

pub fn is_none(&self) -> bool

Returns whether a handle is absent.

pub fn as_raw_handle(&self) -> Option<fdf_handle_t>

Returns the underlying fdf_handle_t, if any.
