Struct fidl_fuchsia_ui_gfx::SetDisplayRotationCmdHack

#[repr(C)]
pub struct SetDisplayRotationCmdHack {
    pub compositor_id: u32,
    pub rotation_degrees: u32,
}

Depending on the device, the display might be rotated with respect to what the lower level device controller considers the physical orientation of pixels. The compositors and layers must be in alignment with the underlying physical orientation which means that for certain operations like screenshotting, they cannot provide results with the accurate orientation unless they have information about how the higher-level display is orienting the screen. The only legal values for the rotation are 0, 90, 180, and 270, which are each applied counterclockwise.

Fields

compositor_id: u32

rotation_degrees: u32

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

Formats the value using the given formatter.

impl Decode<SetDisplayRotationCmdHack> for SetDisplayRotationCmdHack

fn new_empty() -> Self

Creates a valid instance of Self. The specific value does not matter, since it will be overwritten by decode.

unsafe fn decode( &mut self, decoder: &mut Decoder<'_>, offset: usize, _depth: Depth ) -> Result<()>

Decodes an object of type T from the decoder’s buffers into self.

impl Encode<SetDisplayRotationCmdHack> for &SetDisplayRotationCmdHack

unsafe fn encode( self, encoder: &mut Encoder<'_>, offset: usize, _depth: Depth ) -> Result<()>

Encodes the object into the encoder’s buffers. Any handles stored in the object are swapped for Handle::INVALID.

impl<T0: Encode<u32>, T1: Encode<u32>> Encode<SetDisplayRotationCmdHack> for (T0, T1)

unsafe fn encode( self, encoder: &mut Encoder<'_>, offset: usize, depth: Depth ) -> Result<()>

Encodes the object into the encoder’s buffers. Any handles stored in the object are swapped for Handle::INVALID.

impl FromBytes for SetDisplayRotationCmdHackwhere u32: FromBytes,

fn read_from<B>(bytes: B) -> Option<Self>where B: ByteSlice, Self: Sized,

Reads a copy of Self from bytes.

fn read_from_prefix<B>(bytes: B) -> Option<Self>where B: ByteSlice, Self: Sized,

Reads a copy of Self from the prefix of bytes.

fn read_from_suffix<B>(bytes: B) -> Option<Self>where B: ByteSlice, Self: Sized,

fn new_zeroed() -> Selfwhere Self: Sized,

Creates an instance of Self from zeroed bytes.

impl Hash for SetDisplayRotationCmdHack

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 SetDisplayRotationCmdHack

fn cmp(&self, other: &SetDisplayRotationCmdHack) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<SetDisplayRotationCmdHack> for SetDisplayRotationCmdHack

fn eq(&self, other: &SetDisplayRotationCmdHack) -> 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<SetDisplayRotationCmdHack> for SetDisplayRotationCmdHack

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

impl TypeMarker for SetDisplayRotationCmdHack

type Owned = SetDisplayRotationCmdHack

The owned Rust type which this FIDL type decodes into.

fn inline_align(_context: Context) -> usize

Returns the minimum required alignment of the inline portion of the encoded object. It must be a (nonzero) power of two.

fn inline_size(_context: Context) -> usize

Returns the size of the inline portion of the encoded object, including padding for alignment. Must be a multiple of inline_align.

fn encode_is_copy() -> bool

Returns true if the memory layout of Self::Owned matches the FIDL wire format and encoding requires no validation. When true, we can optimize encoding arrays and vectors of Self::Owned to a single memcpy.

fn decode_is_copy() -> bool

Returns true if the memory layout of Self::Owned matches the FIDL wire format and decoding requires no validation. When true, we can optimize decoding arrays and vectors of Self::Owned to a single memcpy.

impl ValueTypeMarker for SetDisplayRotationCmdHack

type Borrowed<'a> = &'a <SetDisplayRotationCmdHack as TypeMarker>::Owned

The Rust type to use for encoding. This is a particular Encode<Self> type cheaply obtainable from &Self::Owned. There are three cases:

fn borrow<'a>(value: &'a <Self as TypeMarker>::Owned) -> Self::Borrowed<'a>

Cheaply converts from &Self::Owned to Self::Borrowed.
