Struct 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 associated with the VSync event.

timestamp: i64

The time when the VSync occurred.

The accurrancy of this timestamp depends on the display hardware.

applied_config_stamp: ConfigStamp

Identifies the lastest configuration fully applied to the display.

Guaranteed to be a valid value.

If a configuration contains images that are still waiting to be ready, that configuration will be only partially applied (without the waiting image). That configuration’s stamp will not be reported here.

cookie: VsyncAckCookie

Used to acknowledge the receipt of VSync events.

A value of zero means no acknowledgement is required by the client.

Each non-zero cookie must be acknowledged immediately, via a call to [Coordinator.AcknowledgeVsync]. Cookies must be acknowledged even if the client does not change the display’s configuration.

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<(), Error>

Formats the value using the given formatter.

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

where D: ResourceDialect,

fn new_empty() -> CoordinatorListenerOnVsyncRequest

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<(), Error>

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

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

where D: ResourceDialect,

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

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

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

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: &<CoordinatorListenerOnVsyncRequest as TypeMarker>::Owned, ) -> <CoordinatorListenerOnVsyncRequest as ValueTypeMarker>::Borrowed<'_>

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