Struct SendSizeChangeHintCmdHack

pub struct SendSizeChangeHintCmdHack {
    pub node_id: u32,
    pub width_change_factor: f32,
    pub height_change_factor: f32,
}

Sends a hint about a pending size change to the given node and all nodes below. This is generally sent before an animation.

width_change_factor and height_change_factor is how much bigger or smaller the item is expected to be in the near future. This one number encapsulate both changes in scale, as well as changes to layout width and height.

Fields

node_id: u32

width_change_factor: f32

height_change_factor: f32

Trait Implementations

impl Clone for SendSizeChangeHintCmdHack

fn clone(&self) -> SendSizeChangeHintCmdHack

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SendSizeChangeHintCmdHack

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

Formats the value using the given formatter.

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

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<SendSizeChangeHintCmdHack, D> for &SendSizeChangeHintCmdHack

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<u32, D>, T1: Encode<f32, D>, T2: Encode<f32, D>> Encode<SendSizeChangeHintCmdHack, D> for (T0, T1, T2)

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 SendSizeChangeHintCmdHack

fn eq(&self, other: &SendSizeChangeHintCmdHack) -> 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 PartialOrd for SendSizeChangeHintCmdHack

fn partial_cmp(&self, other: &SendSizeChangeHintCmdHack) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl TypeMarker for SendSizeChangeHintCmdHack

type Owned = SendSizeChangeHintCmdHack

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 SendSizeChangeHintCmdHack

type Borrowed<'a> = &'a SendSizeChangeHintCmdHack

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.
