Struct JsMesh 

pub struct JsMesh { /* private fields */ }

A triangle mesh exposed to JavaScript.

Positions and normals are flattened to [x, y, z, x, y, z, ...] format for efficient WASM transfer and direct use as GPU vertex buffers.

Implementations

impl JsMesh

pub fn positions(&self) -> Vec<f64>

Flattened vertex positions as [x, y, z, ...].

pub fn normals(&self) -> Vec<f64>

Flattened per-vertex normals as [nx, ny, nz, ...].

pub fn indices(&self) -> Vec<u32>

Triangle indices (groups of 3).

pub fn vertex_count(&self) -> u32

Number of vertices in the mesh.

pub fn triangle_count(&self) -> u32

Number of triangles in the mesh.

pub fn packed_buffer(&self) -> Vec<u8>

Return all mesh data in a single packed buffer for efficient FFI transfer.

Layout: [pos_bytes: u32 LE, norm_bytes: u32 LE, idx_bytes: u32 LE, positions: f64 LE..., normals: f64 LE..., indices: u32 LE...]

This avoids three separate .clone() + FFI copies that the individual getters (positions, normals, indices) would incur.

Trait Implementations

impl Debug for JsMesh

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

Formats the value using the given formatter.

impl From<JsMesh> for JsValue

fn from(value: JsMesh) -> Self

Converts to this type from the input type.

impl From<TriangleMesh> for JsMesh

fn from(mesh: TriangleMesh) -> Self

Converts to this type from the input type.

impl FromWasmAbi for JsMesh

type Abi = WasmPtr<WasmRefCell<JsMesh>>

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

unsafe fn from_abi(js: Self::Abi) -> Self

Recover a Self from Self::Abi.

impl IntoWasmAbi for JsMesh

type Abi = WasmPtr<WasmRefCell<JsMesh>>

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

fn into_abi(self) -> Self::Abi

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

impl LongRefFromWasmAbi for JsMesh

type Abi = WasmPtr<WasmRefCell<JsMesh>>

Same as RefFromWasmAbi::Abi

type Anchor = RcRef<JsMesh>

Same as RefFromWasmAbi::Anchor

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

Same as RefFromWasmAbi::ref_from_abi

impl OptionFromWasmAbi for JsMesh

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 JsMesh

fn none() -> Self::Abi

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

impl RefFromWasmAbi for JsMesh

type Abi = WasmPtr<WasmRefCell<JsMesh>>

The Wasm ABI type references to Self are recovered from.

type Anchor = RcRef<JsMesh>

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 JsMesh

type Abi = WasmPtr<WasmRefCell<JsMesh>>

Same as RefFromWasmAbi::Abi

type Anchor = RcRefMut<JsMesh>

Same as RefFromWasmAbi::Anchor

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

Same as RefFromWasmAbi::ref_from_abi

impl SupportsConstructor for JsMesh

impl TryFromJsValue for JsMesh

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

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

Performs the conversion.

impl VectorFromWasmAbi for JsMesh

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

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