Struct script::iframe_collection::IFrameCollection

pub(crate) struct IFrameCollection {
    document_version: Cell<u64>,
    iframes: Vec<IFrame>,
}

Fields

document_version: Cell<u64>

The version of the Document that this collection refers to. When the versions do not match, the collection will need to be rebuilt.

iframes: Vec<IFrame>

The <iframe>s in the collection.

Implementations

impl IFrameCollection

pub(crate) fn validate(&mut self, document: &Document)

Validate that the collection is up-to-date with the given Document. If it isn’t up-to-date rebuild it.

pub(crate) fn get( &self, browsing_context_id: BrowsingContextId, ) -> Option<&IFrame>

pub(crate) fn get_mut( &mut self, browsing_context_id: BrowsingContextId, ) -> Option<&mut IFrame>

pub(crate) fn set_size( &mut self, browsing_context_id: BrowsingContextId, new_size: Size2D<f32, CSSPixel>, ) -> Option<Size2D<f32, CSSPixel>>

Set the size of an <iframe> in the collection given its BrowsingContextId and the new size. Returns the old size.

pub(crate) fn handle_new_iframe_sizes_after_layout( &mut self, new_iframe_sizes: IFrameSizes, device_pixel_ratio: Scale<f32, CSSPixel, DevicePixel>, ) -> Vec<IFrameSizeMsg>

Update the recorded iframe sizes of the contents of layout. Return a [Vec<IFrameSizeMsg] containing the messages to send to the Constellation. A message is only sent when the size actually changes.

pub(crate) fn iter( &self, ) -> impl Iterator<Item = Root<Dom<HTMLIFrameElement>>> + use<'_>

Trait Implementations

impl Default for IFrameCollection

fn default() -> IFrameCollection

Returns the “default value” for a type.

impl MallocSizeOf for IFrameCollection

fn size_of(&self, ops: &mut MallocSizeOfOps) -> usize

Measure the heap usage of all descendant heap-allocated structures, but not the space taken up by the value itself.

impl Traceable for IFrameCollection

unsafe fn trace(&self, tracer: *mut JSTracer)

Trace self.
