Struct MazeSolutionWasm

pub struct MazeSolutionWasm {
    pub solution: MazeSolution,
}

Web assembly representation of a maze solution

Fields

solution: MazeSolution

Implementations

impl MazeSolutionWasm

pub fn get_path_points(&self) -> Array

Returns the array of points (if any) associated with the maze solution

Returns

This function will return an array of Javascript objects defining each point in the solution. Each solution point object has the folllowing properties:

• row - zero-based row index for the solution point
• col - zero-based column index for the solution point

Examples

Initialize a maze from a JSON string, then attempt to solve it and, if successful, print the maze solution path’s points

// Javascript <script> content:

import init, { MazeWasm } from 'maze_wasm.js';

async function run() {
    await init();

    try {
        let maze = new MazeWasm();
        maze.from_json(`{
            \"id\":\"maze_id\",
            \"name\":\"test\",
            \"definition\": {
                \"grid\":[
                    [\"S\", \"W\", \" \", \" \", \"W\"],
                    [\" \", \"W\", \" \", \"W\", \" \"],
                    [\" \", \" \", \" \", \"W\", \"F\"],
                    [\"W\", \" \", \"W\", \" \", \" \"],
                    [\" \", \" \", \" \", \"W\", \" \"],
                    [\"W\", \"W\", \" \", \" \", \" \"],
                    [\"W\", \"W\", \" \", \"W\", \" \"]
                ]
        }}`);
        let solution = maze.solve();
        let solutionPoints = solution.get_path_points();
        console.log("Successfully solved maze. Solution points are: ", solutionPoints);
    } catch (e) {
        console.error("Operation failed: ", e);
    }
}
run();

Trait Implementations

impl From<MazeSolutionWasm> for JsValue

fn from(value: MazeSolutionWasm) -> Self

Converts to this type from the input type.

impl FromWasmAbi for MazeSolutionWasm

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 MazeSolutionWasm

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 MazeSolutionWasm

type Abi = u32

Same as RefFromWasmAbi::Abi

type Anchor = RcRef<MazeSolutionWasm>

Same as RefFromWasmAbi::Anchor

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

Same as RefFromWasmAbi::ref_from_abi

impl OptionFromWasmAbi for MazeSolutionWasm

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 MazeSolutionWasm

fn none() -> Self::Abi

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

impl RefFromWasmAbi for MazeSolutionWasm

type Abi = u32

The Wasm ABI type references to Self are recovered from.

type Anchor = RcRef<MazeSolutionWasm>

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 MazeSolutionWasm

type Abi = u32

Same as RefFromWasmAbi::Abi

type Anchor = RcRefMut<MazeSolutionWasm>

Same as RefFromWasmAbi::Anchor

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

Same as RefFromWasmAbi::ref_from_abi

impl TryFromJsValue for MazeSolutionWasm

type Error = JsValue

The type returned in the event of a conversion error.

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

Performs the conversion.

impl VectorFromWasmAbi for MazeSolutionWasm

type Abi = <Box<[JsValue]> as FromWasmAbi>::Abi

unsafe fn vector_from_abi(js: Self::Abi) -> Box<[MazeSolutionWasm]>

impl VectorIntoJsValue for MazeSolutionWasm

fn vector_into_jsvalue(vector: Box<[MazeSolutionWasm]>) -> JsValue

impl VectorIntoWasmAbi for MazeSolutionWasm
