Struct RenderFrame 

pub struct RenderFrame {
    pub commands: Vec<Canvas2DCommand>,
}

A frame’s worth of render commands.

Fields

commands: Vec<Canvas2DCommand>

The commands to execute this frame.

Implementations

impl RenderFrame

pub fn new() -> Self

Creates a new empty render frame.

pub fn with_capacity(capacity: usize) -> Self

Creates a render frame with an initial capacity.

pub fn clear(&mut self)

Clears all commands.

pub fn push(&mut self, cmd: Canvas2DCommand)

Adds a command to the frame.

pub fn clear_screen(&mut self, color: Color)

Clears the canvas with a color.

pub fn fill_rect( &mut self, x: f32, y: f32, width: f32, height: f32, color: Color, )

Draws a filled rectangle.

pub fn fill_circle(&mut self, x: f32, y: f32, radius: f32, color: Color)

Draws a filled circle.

pub fn fill_text( &mut self, text: &str, x: f32, y: f32, font: &str, color: Color, )

Draws text.

pub fn fill_text_aligned( &mut self, text: &str, x: f32, y: f32, font: &str, color: Color, align: TextAlign, baseline: TextBaseline, )

Draws text with alignment options.

pub fn line( &mut self, x1: f32, y1: f32, x2: f32, y2: f32, color: Color, line_width: f32, )

Draws a line.

pub fn stroke_rect( &mut self, x: f32, y: f32, width: f32, height: f32, color: Color, line_width: f32, )

Strokes a rectangle outline.

pub fn len(&self) -> usize

Returns the number of commands.

pub fn is_empty(&self) -> bool

Checks if the frame has no commands.

pub fn to_json(&self) -> Result<String, Error>

Serializes the frame to JSON.

Errors

Returns an error if serialization fails.

pub fn to_json_pretty(&self) -> Result<String, Error>

Serializes the frame to pretty-printed JSON.

Errors

Returns an error if serialization fails.

Trait Implementations

impl Clone for RenderFrame

fn clone(&self) -> RenderFrame

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RenderFrame

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

Formats the value using the given formatter.

impl Default for RenderFrame

fn default() -> RenderFrame

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for RenderFrame

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for RenderFrame

fn eq(&self, other: &RenderFrame) -> 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 RenderFrame

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
