Struct OnNextFrameBeginValues

pub struct OnNextFrameBeginValues {
    pub additional_present_credits: Option<u32>,
    pub future_presentation_infos: Option<Vec<PresentationInfo>>,
    /* private fields */
}

Fields that a client needs in order to produce its next frame, returned in [OnNextFrameBegin]. Each field is guaranteed to be set and contain valid information.

Fields

additional_present_credits: Option<u32>

The number of additional [Present] calls allowed to the client so that they can call [Present] further times. This is a delta in the present credit budget, not the absolute number of present credits.

future_presentation_infos: Option<Vec<PresentationInfo>>

Information about future presentation and latch times that a client may aim for precise scheduling behavior.

Trait Implementations

impl Clone for OnNextFrameBeginValues

fn clone(&self) -> OnNextFrameBeginValues

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for OnNextFrameBeginValues

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

Formats the value using the given formatter.

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

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 Default for OnNextFrameBeginValues

fn default() -> OnNextFrameBeginValues

Returns the “default value” for a type.

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

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 OnNextFrameBeginValues

fn eq(&self, other: &OnNextFrameBeginValues) -> 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 OnNextFrameBeginValues

type Owned = OnNextFrameBeginValues

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 OnNextFrameBeginValues

type Borrowed<'a> = &'a OnNextFrameBeginValues

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.
