Struct RenderDataStream 

pub struct RenderDataStream { /* private fields */ }

A recorded sequence of drawing operations with its resource table.

Implementations

impl RenderDataStream

pub fn new() -> Self

pub fn opcodes(&self) -> &[u8]

The recorded operations.

pub fn opcode_length(&self) -> usize

The number of bytes recorded: the position a later rewind can return to.

pub fn depth(&self) -> i32

The current scope depth.

pub fn max_depth(&self) -> i32

The deepest scope nesting recorded.

pub fn resource_count(&self) -> usize

pub fn get_resource(&self, handle: i32) -> Option<&RenderDataResource>

pub fn rewind(&mut self, length: usize, depth: i32)

Drops everything recorded after position length and restores the scope depth.

pub fn dispose_resources(&self)

Releases the resources the stream holds a reference to on behalf of their owners.

pub fn draw_line( &mut self, server_pen: Option<RenderDataResource>, client_pen: Option<RenderDataResource>, p1: Point, p2: Point, )

pub fn draw_rectangle( &mut self, server_brush: Option<RenderDataResource>, server_pen: Option<RenderDataResource>, client_pen: Option<RenderDataResource>, rect: RoundedRect, box_shadows: &BoxShadows, )

pub fn draw_ellipse( &mut self, server_brush: Option<RenderDataResource>, server_pen: Option<RenderDataResource>, client_pen: Option<RenderDataResource>, rect: Rect, )

pub fn draw_geometry( &mut self, server_brush: Option<RenderDataResource>, server_pen: Option<RenderDataResource>, client_pen: Option<RenderDataResource>, geometry: Option<RenderDataResource>, )

pub fn draw_glyph_run( &mut self, server_brush: Option<RenderDataResource>, glyph_run: Option<Arc<dyn IGlyphRunImpl>>, )

Records a glyph run. The table entry is a new counted reference to it (upstream’s caller passes PlatformImpl.Clone()).

pub fn draw_bitmap( &mut self, bitmap: Option<RefCounted<SharedBitmapImpl>>, opacity: f64, source_rect: Rect, dest_rect: Rect, )

Records a bitmap. The table entry is a new counted reference to it (upstream’s caller passes source.Clone()).

pub fn draw_custom(&mut self, operation: Option<Arc<dyn ICustomDrawOperation>>)

pub fn push_clip(&mut self, clip: RoundedRect)

pub fn push_geometry_clip(&mut self, geometry: Option<RenderDataResource>)

pub fn push_opacity(&mut self, opacity: f64)

pub fn push_opacity_mask( &mut self, server_brush: Option<RenderDataResource>, bounds: Rect, )

pub fn push_transform(&mut self, matrix: Matrix)

pub fn push_render_options(&mut self, options: RenderOptions)

pub fn push_text_options(&mut self, text_options: TextOptions)

pub fn push_effect( &mut self, effect: Option<Arc<dyn IImmutableEffect>>, bounds: Rect, )

pub fn pop(&mut self)

pub fn serialize_to(&self, writer: &mut BatchStreamWriter<'_>)

Writes the stream to a batch. Resources with a server-side counterpart are sent as the counterpart’s id; client-only resources keep their slot but are not sent.

pub fn deserialize_from( &mut self, reader: &mut BatchStreamReader<'_>, resolve: &dyn Fn(ServerObjectId) -> Option<Rc<dyn IServerObject>>, )

Reads a stream from a batch on the server. resolve maps the id of a server object to the object.

pub fn visit<V: IRenderDataVisitor>(&self, visitor: &mut V)

Walks the recorded operations.

pub fn visit_with_scopes<V: IRenderDataVisitor>( &self, visitor: &mut V, scopes: &mut Vec<V::Scope>, )

Walks the recorded operations using a caller-provided scope stack, which lets a caller that visits often reuse the allocation (upstream keeps the scopes on the stack).

pub fn dispose(&mut self)

Releases the stream.

impl RenderDataStream

pub fn calculate_bounds(&self) -> Option<Rect>

The bounds of everything the stream draws, or None if it draws nothing.

impl RenderDataStream

pub fn hit_test(&self, point: Point) -> bool

Whether anything recorded is hit at a point.

pub fn hit_test_geometry(&self, geometry: &Ref<Geometry>) -> IntersectionResult

How the recorded content intersects a geometry.

impl RenderDataStream

pub fn replay(&self, context: &mut dyn IDrawingContextImpl)

Replays the recorded operations onto a platform drawing context.

pub fn replay_with_scopes( &self, context: &mut dyn IDrawingContextImpl, scopes: &mut Vec<ReplayScope>, )

Like replay, with a reusable scope stack.

Trait Implementations

impl Default for RenderDataStream

fn default() -> Self

Returns the “default value” for a type.
