Struct gc_nes_web::WebNes

pub struct WebNes { /* fields omitted */ }

Structure used the represent the NES itself in WASM.

Implementations

impl WebNes

pub fn new(cartridge: WebCartridge) -> WebNes

Creates a new NES instance with no connected controllers.

pub fn cycle(&mut self)

Runs a single cycle on the NES

pub fn frame(&mut self) -> Vec<u8>

Runs as many cycles as necessary to complete the current frame. Returns the frame as a Vector of bytes, with each pixel of the NES screen represented by four bytes in RGBA order.

pub fn get_screen(&mut self) -> Vec<u8>

Gets the current state of the screen from the PPU's screen buffer. Returns the frame as a Vector of bytes, with each pixel of the NES screen represented by four bytes in RGBA order.

pub fn update_controller_one(&mut self, controller_state: u8)

Updates the state of the input device connected to the first port.

pub fn update_controller_two(&mut self, controller_state: u8)

Updates the state of the input device connected to the first port.

pub fn reset(&mut self)

Resets the state of the NES.

Trait Implementations

impl From<WebNes> for JsValue

fn from(value: WebNes) -> Self

Performs the conversion.

impl FromWasmAbi for WebNes

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 WebNes

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 OptionFromWasmAbi for WebNes

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 WebNes

fn none() -> Self::Abi

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

impl RefFromWasmAbi for WebNes

type Abi = u32

The wasm ABI type references to Self are recovered from.

type Anchor = Ref<'static, WebNes>

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 WebNes

type Abi = u32

Same as RefFromWasmAbi::Abi

type Anchor = RefMut<'static, WebNes>

Same as RefFromWasmAbi::Anchor

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

Same as RefFromWasmAbi::ref_from_abi

impl WasmDescribe for WebNes
