Struct WatchResponse

pub struct WatchResponse {
    pub epoch_end: Option<i64>,
    pub updates: Option<Vec<ViewTreeSnapshot>>,
    pub error: Option<Error>,
    /* private fields */
}

Response for fuchsia.ui.observation.geometry.ViewTreeWatcher.Watch.

Fields

epoch_end: Option<i64>

When the response is sent. Timebase is monotonic time.

updates: Option<Vec<ViewTreeSnapshot>>

A list of most recent updates for a particular view.

error: Option<Error>

Only set if an error condition is detected. If unset, the client may assume that updates has complete information over its epoch.

Trait Implementations

impl Clone for WatchResponse

fn clone(&self) -> WatchResponse

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for WatchResponse

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

Formats the value using the given formatter.

impl<D> Decode<WatchResponse, D> for WatchResponse

where D: ResourceDialect,

fn new_empty() -> WatchResponse

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 Default for WatchResponse

fn default() -> WatchResponse

Returns the “default value” for a type.

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

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 WatchResponse

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

type Owned = WatchResponse

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 WatchResponse

type Borrowed<'a> = &'a WatchResponse

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

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