Struct DisplayList 

pub struct DisplayList {
    pub ops: Vec<DisplayOp>,
    pub bounds: LayoutRect,
}

An ordered list of DisplayOps ready to be consumed by a Renderer.

The display list is the final output of the Fission pipeline before pixels. It is serializable, so it can be sent to a separate render thread or process.

Example

use fission_render::*;

let bounds = LayoutRect::new(0.0, 0.0, 800.0, 600.0);
let mut list = DisplayList::new(bounds);

list.push(DisplayOp::Save);
list.push(DisplayOp::DrawRect {
    rect: LayoutRect::new(10.0, 10.0, 100.0, 50.0),
    fill: Some(Fill { color: Color { r: 0, g: 0, b: 0, a: 255 } }),
    stroke: None,
    corner_radius: 0.0,
    shadow: None,
    bounds: LayoutRect::new(10.0, 10.0, 100.0, 50.0),
    node_id: None,
});
list.push(DisplayOp::Restore);

assert_eq!(list.ops.len(), 3);

Fields

ops: Vec<DisplayOp>

The ordered sequence of rendering commands.

bounds: LayoutRect

The bounding rectangle of the entire scene (typically the viewport).

Implementations

impl DisplayList

pub fn new(bounds: LayoutRect) -> Self

Creates an empty display list with the given scene bounds.

pub fn push(&mut self, op: DisplayOp)

Appends a display operation to the end of the list.

Trait Implementations

impl Clone for DisplayList

fn clone(&self) -> DisplayList

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DisplayList

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for DisplayList

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for DisplayList

fn eq(&self, other: &DisplayList) -> 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 Serialize for DisplayList

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
