Enum fidl_fuchsia_ui_gfx::Event

pub enum Event {
    Metrics(MetricsEvent),
    SizeChangeHint(SizeChangeHintEvent),
    ImportUnbound(ImportUnboundEvent),
    ViewConnected(ViewConnectedEvent),
    ViewDisconnected(ViewDisconnectedEvent),
    ViewHolderDisconnected(ViewHolderDisconnectedEvent),
    ViewAttachedToScene(ViewAttachedToSceneEvent),
    ViewDetachedFromScene(ViewDetachedFromSceneEvent),
    ViewPropertiesChanged(ViewPropertiesChangedEvent),
    ViewStateChanged(ViewStateChangedEvent),
    ViewHolderConnected(ViewHolderConnectedEvent),
}

These are all of the types of events which can be reported by a Session. Use SetEventMaskCmd to enable event delivery for a resource.

Variants

Metrics(MetricsEvent)

Events which are controlled by a mask.

SizeChangeHint(SizeChangeHintEvent)

ImportUnbound(ImportUnboundEvent)

Events which are always delivered, regardless of mask.

ViewConnected(ViewConnectedEvent)

ViewDisconnected(ViewDisconnectedEvent)

ViewHolderDisconnected(ViewHolderDisconnectedEvent)

ViewAttachedToScene(ViewAttachedToSceneEvent)

ViewDetachedFromScene(ViewDetachedFromSceneEvent)

ViewPropertiesChanged(ViewPropertiesChangedEvent)

ViewStateChanged(ViewStateChangedEvent)

ViewHolderConnected(ViewHolderConnectedEvent)

Implementations

impl Event

pub fn ordinal(&self) -> u64

pub fn is_unknown(&self) -> bool

👎Deprecated: Strict unions should not use is_unknown

Trait Implementations

impl Clone for Event

fn clone(&self) -> Event

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Event

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

Formats the value using the given formatter.

impl Decode<Event> for Event

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<Event> for &Event

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 PartialEq<Event> for Event

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

fn partial_cmp(&self, other: &Event) -> 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 Event

type Owned = Event

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 Event

type Borrowed<'a> = &'a <Event 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.
