Implementations

impl DisplayListBuilder[src]

pub fn new(pipeline_id: PipelineId, content_size: LayoutSize) -> Self[src]

pub fn with_capacity(
    pipeline_id: PipelineId,
    content_size: LayoutSize,
    capacity: usize
) -> Self
[src]

pub fn content_size(&self) -> LayoutSize[src]

Return the content size for this display list

pub fn save(&mut self)[src]

Saves the current display list state, so it may be restore()'d.

Conditions:

  • Doesn't support popping clips that were pushed before the save.
  • Doesn't support nested saves.
  • Must call clear_save() if the restore becomes unnecessary.

pub fn restore(&mut self)[src]

Restores the state of the builder to when save() was last called.

pub fn clear_save(&mut self)[src]

Discards the builder's save (indicating the attempted operation was successful).

pub fn emit_display_list<W>(
    &mut self,
    indent: usize,
    range: Range<Option<usize>>,
    sink: W
) -> usize where
    W: Write
[src]

Emits a debug representation of display items in the list, for debugging purposes. If the range's start parameter is specified, only display items starting at that index (inclusive) will be printed. If the range's end parameter is specified, only display items before that index (exclusive) will be printed. Calling this function with end <= start is allowed but is just a waste of CPU cycles. The function emits the debug representation of the selected display items, one per line, with the given indent, to the provided sink object. The return value is the total number of items in the display list, which allows the caller to subsequently invoke this function to only dump the newly-added items.

pub fn dump_serialized_display_list(&mut self)[src]

Print the display items in the list to stdout.

pub fn push_item_to_section(
    &mut self,
    item: &DisplayItem,
    section: DisplayListSection
)
[src]

pub fn push_item(&mut self, item: &DisplayItem)[src]

Add an item to the display list.

NOTE: It is usually preferable to use the specialized methods to push display items. Pushing unexpected or invalid items here may result in WebRender panicking or behaving in unexpected ways.

pub fn push_iter<I>(&mut self, iter: I) where
    I: IntoIterator,
    I::IntoIter: ExactSizeIterator,
    I::Item: Poke
[src]

Push items from an iterator to the display list.

NOTE: Pushing unexpected or invalid items to the display list may result in panic and confusion.

    color_depth: ColorDepth,
    color_space: YuvColorSpace,
    color_range: ColorRange,
    image_rendering: ImageRendering
)
[src]

Push a yuv image. All planar data in yuv image should use the same buffer type.

pub fn push_text(
    &mut self,
    common: &CommonItemProperties,
    bounds: LayoutRect,
    glyphs: &[GlyphInstance],

pub fn create_gradient(
    &mut self,
    start_point: LayoutPoint,
    end_point: LayoutPoint,
    stops: Vec<GradientStop>,
    extend_mode: ExtendMode
) -> Gradient
[src]

NOTE: gradients must be pushed in the order they're created because create_gradient stores the stops in anticipation.

pub fn create_radial_gradient(
    &mut self,
    center: LayoutPoint,
    radius: LayoutSize,
    stops: Vec<GradientStop>,
    extend_mode: ExtendMode
) -> RadialGradient
[src]

NOTE: gradients must be pushed in the order they're created because create_gradient stores the stops in anticipation.

pub fn create_conic_gradient(
    &mut self,

    stops: Vec<GradientStop>,
    extend_mode: ExtendMode
) -> ConicGradient
[src]

NOTE: gradients must be pushed in the order they're created because create_gradient stores the stops in anticipation.

    &mut self,
    common: &CommonItemProperties,
    bounds: LayoutRect,
    gradient: Gradient,
    tile_size: LayoutSize,
    tile_spacing: LayoutSize
)
[src]

Pushes a linear gradient to be displayed.

The gradient itself is described in the gradient parameter. It is drawn on a "tile" with the dimensions from tile_size. These tiles are now repeated to the right and to the bottom infinitely. If tile_spacing is not zero spacers with the given dimensions are inserted between the tiles as seams.

The origin of the tiles is given in layout.rect.origin. If the gradient should only be displayed once limit the layout.rect.size to a single tile. The gradient is only visible within the local clip.

pub fn push_radial_gradient(
    &mut self,
    common: &CommonItemProperties,
    bounds: LayoutRect,
    gradient: RadialGradient,
    tile_size: LayoutSize,
