Struct ContentBounds 

pub struct ContentBounds {
    pub size: Option<SizeU>,
    pub origin: Option<Vec_>,
    /* private fields */
}

Defines the size and position of a piece of graphical content.

The bounds of the content are assumed to be rectangular.

Fields

size: Option<SizeU>

The size of the content, defined in its parent view’s coordinate space.

For example, a parent view with size 1280x800 is assumed to have a useful coordinate space from (0, 0) to (1280, 800). A piece of content that’s one-fourth the area of the parent view would have size 640x400.

origin: Option<Vec_>

The location of the top-left corner of the content’s origin, defined in the parent view’s coordinate space.

Returning to the example above, we could position the content to cover the bottom-right quadrant of the parent by assigning an origin of (640, 400).

Trait Implementations

impl Clone for ContentBounds

fn clone(&self) -> ContentBounds

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ContentBounds

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

Formats the value using the given formatter.

impl<D> Decode<ContentBounds, D> for ContentBounds

where D: ResourceDialect,

fn new_empty() -> ContentBounds

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 ContentBounds

fn default() -> ContentBounds

Returns the “default value” for a type.

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

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 ContentBounds

fn eq(&self, other: &ContentBounds) -> 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 Persistable for ContentBounds

impl StructuralPartialEq for ContentBounds

impl TypeMarker for ContentBounds

type Owned = ContentBounds

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 ContentBounds

type Borrowed<'a> = &'a ContentBounds

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

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