Struct WebPlatform 

pub struct WebPlatform { /* private fields */ }

The main web platform struct exposed to JavaScript via wasm-bindgen.

This handles the game loop, input processing, and render command generation. All computation happens in Rust; JavaScript only forwards events and draws.

Implementations

impl WebPlatform

pub fn new(config_json: &str) -> Result<Self, JsValue>

Creates a new WebPlatform with configuration from JSON.

Arguments

• config_json - JSON string with configuration

Errors

Returns a JavaScript error if the configuration is invalid.

pub fn new_default() -> Self

Creates a new WebPlatform with default configuration.

pub fn set_canvas_offset(&mut self, x: f32, y: f32)

Sets the canvas offset from viewport origin.

pub fn frame(&mut self, timestamp: f64, input_events_json: &str) -> String

Processes a single frame.

This is called from requestAnimationFrame. All game logic runs here.

Arguments

• timestamp - DOMHighResTimeStamp from requestAnimationFrame
• input_events_json - JSON array of input events since last frame

Returns

JSON string with render commands for Canvas2D execution.

pub fn resize(&mut self, width: u32, height: u32)

Handles canvas resize.

Arguments

• width - New canvas width in pixels
• height - New canvas height in pixels

pub fn get_config(&self) -> String

Returns the current configuration as JSON.

pub fn get_stats(&self) -> String

Returns current debug statistics as JSON.

pub fn reset_timer(&mut self)

Resets the timer (useful when tab becomes visible again).

pub fn get_ai_model(&self) -> String

Returns the AI model as JSON string for download.

pub fn get_ai_info(&self) -> String

Returns AI model metadata and current state as JSON.

pub fn set_ai_difficulty(&mut self, level: u8)

Sets the AI difficulty level (0-9).

pub fn get_ai_difficulty(&self) -> u8

Gets the current AI difficulty level.

pub fn set_speed(&mut self, speed: u32)

Sets the speed multiplier (1, 5, 10, 50, 100, 1000).

pub fn get_speed(&self) -> u32

Gets the current speed multiplier value.

pub fn set_game_mode(&mut self, mode: &str)

Sets the game mode (“demo”, “1p”, “2p”).

pub fn get_game_mode(&self) -> String

Gets the current game mode as string.

impl WebPlatform

pub fn new_for_test(config: WebConfig) -> Self

Creates a platform without wasm-bindgen (for testing).

pub const fn input(&self) -> &InputState

Returns a reference to the input state (for testing).

pub fn input_mut(&mut self) -> &mut InputState

Returns a mutable reference to the input state (for testing).

pub const fn timer(&self) -> &FrameTimer

Returns a reference to the frame timer (for testing).

pub const fn pong(&self) -> &PongGame

Returns a reference to the Pong game (for testing).

pub const fn tracer(&self) -> &GameTracer

Returns a reference to the game tracer (for testing).

pub const fn config(&self) -> &WebConfig

Returns a reference to the config (for testing).

Trait Implementations

impl From<WebPlatform> for JsValue

fn from(value: WebPlatform) -> Self

Converts to this type from the input type.

impl FromWasmAbi for WebPlatform

type Abi = u32

The Wasm ABI type that this converts from when coming back out from the ABI boundary.

unsafe fn from_abi(js: u32) -> Self

Recover a Self from Self::Abi.

impl IntoWasmAbi for WebPlatform

type Abi = u32

The Wasm ABI type that this converts into when crossing the ABI boundary.

fn into_abi(self) -> u32

Convert self into Self::Abi so that it can be sent across the wasm ABI boundary.

impl LongRefFromWasmAbi for WebPlatform

type Abi = u32

Same as RefFromWasmAbi::Abi

type Anchor = RcRef<WebPlatform>

Same as RefFromWasmAbi::Anchor

unsafe fn long_ref_from_abi(js: Self::Abi) -> Self::Anchor

Same as RefFromWasmAbi::ref_from_abi

impl OptionFromWasmAbi for WebPlatform

fn is_none(abi: &Self::Abi) -> bool

Tests whether the argument is a “none” instance. If so it will be deserialized as None, and otherwise it will be passed to FromWasmAbi.

impl OptionIntoWasmAbi for WebPlatform

fn none() -> Self::Abi

Returns an ABI instance indicating “none”, which JS will interpret as the None branch of this option.

impl RefFromWasmAbi for WebPlatform

type Abi = u32

The Wasm ABI type references to Self are recovered from.

type Anchor = RcRef<WebPlatform>

The type that holds the reference to Self for the duration of the invocation of the function that has an &Self parameter. This is required to ensure that the lifetimes don’t persist beyond one function call, and so that they remain anonymous.

unsafe fn ref_from_abi(js: Self::Abi) -> Self::Anchor

Recover a Self::Anchor from Self::Abi.

impl RefMutFromWasmAbi for WebPlatform

type Abi = u32

Same as RefFromWasmAbi::Abi

type Anchor = RcRefMut<WebPlatform>

Same as RefFromWasmAbi::Anchor

unsafe fn ref_mut_from_abi(js: Self::Abi) -> Self::Anchor

Same as RefFromWasmAbi::ref_from_abi

impl TryFromJsValue for WebPlatform

fn try_from_js_value(value: JsValue) -> Result<Self, JsValue>

Performs the conversion.

fn try_from_js_value_ref(value: &JsValue) -> Option<Self>

Performs the conversion.
