Expand description

Settings for the web content in the Frame. Popup Frames created by the Frame will have their settings initialized to the Frame’s current settings.

Fields§

§hide_scrollbars: Option<bool>

Specifies whether scrollbars are hidden for the Frame. If omitted, the default is false.

§autoplay_policy: Option<AutoplayPolicy>

Specifies the autoplay policy for the Frame. If omitted, the default policy is REQUIRE_USER_ACTIVATION.

§theme: Option<ThemeType>

Specifies the color theme reported to web content via the prefers-color-scheme media query. Valid inputs are LIGHT, DARK, and DEFAULT. If omitted, the default is LIGHT theme. Specifying DEFAULT means using the system settings, and requires that the [Context] have the [fuchsia.settings.Display] service. If the service is not available, the [Frame] will disconnect with ZX_ERR_INVALID_ARGS.

§page_scale: Option<f32>

Sets scale factor (zoom level) that should be applied to web content rendered in this frame. Values above 1.0 make all web content (including text and images) larger, while values below 1.0 will make it smaller. In other words, values above 1.0 are used to zoom in and values below 1.0 zoom out. The overall ratio between physical pixel and CSS pixel is a product of the scale set with this method and the scale provided by Scenic (see [fuchsia.ui.gfx.Metrics]). That product is visible to the web content as window.devicePixelRatio. If omitted, the default is 1.0.

This setting does not have any effect on the size of the view on the screen and the resolution at which the view is rendered. Native (non-web) UI elements, such as default scroll bars and default mouse cursor, are not scaled. User may zoom the page further when pinch-zoom is enabled (see [InputTypes.GESTURE_PINCH]).

Trait Implementations§

Formats the value using the given formatter. Read more
source§

impl Decode<ContentAreaSettings> for ContentAreaSettings

source§

fn new_empty() -> Self

Creates a valid instance of Self. The specific value does not matter, since it will be overwritten by decode.
source§

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. Read more
source§

impl Encode<ContentAreaSettings> for &ContentAreaSettings

source§

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. Read more
source§

impl PartialEq for ContentAreaSettings

source§

fn eq(&self, other: &ContentAreaSettings) -> bool

This method tests for self and other values to be equal, and is used by ==.
1.0.0 · source§

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.
source§

impl TypeMarker for ContentAreaSettings

§

type Owned = ContentAreaSettings

The owned Rust type which this FIDL type decodes into.
source§

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.
source§

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. Read more
§

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.
source§

impl ValueTypeMarker for ContentAreaSettings

§

type Borrowed<'a> = &'a ContentAreaSettings
