Struct fidl_fuchsia_hardware_display::CoordinatorListenerOnVsyncRequest

pub struct CoordinatorListenerOnVsyncRequest {
    pub display_id: DisplayId,
    pub timestamp: i64,
    pub applied_config_stamp: ConfigStamp,
    pub cookie: VsyncAckCookie,
}

Fields

display_id: DisplayId

The display on which the Vsync occurred.

timestamp: i64

The time the Vsync occurred.

applied_config_stamp: ConfigStamp

The stamp of the latest configuration that has been applied to the display.

cookie: VsyncAckCookie

If valid, the Coordinator client must acknowledge the Vsync signal immediately upon receipt by calling AcknowledgeVsync(). Failure to acknowledge OnVsync calls will result in the suspension of Vsync event notification.

If a Coordinator client fails to respond to vsync messages, the client will throttle Vsync events. Information about the throttled events is stored in a bounded queue, which drops the oldest events when it reaches its capacity. When the client acknowledges VSync receipt, the coordinator delivers all VSync events for all the entries in the queue.

Trait Implementations

impl Clone for CoordinatorListenerOnVsyncRequest

fn clone(&self) -> CoordinatorListenerOnVsyncRequest

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CoordinatorListenerOnVsyncRequest

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

Formats the value using the given formatter.

impl<D: ResourceDialect> Decode<CoordinatorListenerOnVsyncRequest, D> for CoordinatorListenerOnVsyncRequest

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<'_, D>, offset: usize, _depth: Depth, ) -> Result<()>

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

impl<D: ResourceDialect> Encode<CoordinatorListenerOnVsyncRequest, D> for &CoordinatorListenerOnVsyncRequest

unsafe fn encode( self, encoder: &mut Encoder<'_, D>, 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<D: ResourceDialect, T0: Encode<DisplayId, D>, T1: Encode<i64, D>, T2: Encode<ConfigStamp, D>, T3: Encode<VsyncAckCookie, D>> Encode<CoordinatorListenerOnVsyncRequest, D> for (T0, T1, T2, T3)

unsafe fn encode( self, encoder: &mut Encoder<'_, D>, 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 PartialEq for CoordinatorListenerOnVsyncRequest

fn eq(&self, other: &CoordinatorListenerOnVsyncRequest) -> 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 TypeMarker for CoordinatorListenerOnVsyncRequest

type Owned = CoordinatorListenerOnVsyncRequest

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 CoordinatorListenerOnVsyncRequest

type Borrowed<'a> = &'a CoordinatorListenerOnVsyncRequest

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(value: &<Self as TypeMarker>::Owned) -> Self::Borrowed<'_>

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