Struct JsGroupedMesh 

pub struct JsGroupedMesh { /* private fields */ }

A triangle mesh with per-face triangle grouping, exposed to JavaScript.

The binary counterpart to the JSON tessellateSolidGrouped: positions and normals are packed Float32Arrays and indices/faceOffsets are Uint32Arrays, so the whole mesh crosses the WASM boundary as bulk memory copies instead of a JSON string round-trip. f32 matches what mesh consumers (GPU vertex buffers) use, halving the transfer versus f64.

Implementations

impl JsGroupedMesh

pub fn positions(&self) -> Vec<f32>

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

pub fn normals(&self) -> Vec<f32>

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

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

Triangle indices (groups of 3).

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

Per-face start offsets into indices: faceOffsets[i] is the start of face i, and the final element equals indices.length.

Trait Implementations

impl Debug for JsGroupedMesh

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

Formats the value using the given formatter.

impl From<JsGroupedMesh> for JsValue

fn from(value: JsGroupedMesh) -> Self

Converts to this type from the input type.

impl FromWasmAbi for JsGroupedMesh

type Abi = WasmPtr<WasmRefCell<JsGroupedMesh>>

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 JsGroupedMesh

type Abi = WasmPtr<WasmRefCell<JsGroupedMesh>>

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 JsGroupedMesh

type Abi = WasmPtr<WasmRefCell<JsGroupedMesh>>

Same as RefFromWasmAbi::Abi

type Anchor = RcRef<JsGroupedMesh>

Same as RefFromWasmAbi::Anchor

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

Same as RefFromWasmAbi::ref_from_abi

impl OptionFromWasmAbi for JsGroupedMesh

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 JsGroupedMesh

fn none() -> Self::Abi

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

impl RefFromWasmAbi for JsGroupedMesh

type Abi = WasmPtr<WasmRefCell<JsGroupedMesh>>

The Wasm ABI type references to Self are recovered from.

type Anchor = RcRef<JsGroupedMesh>

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 JsGroupedMesh

type Abi = WasmPtr<WasmRefCell<JsGroupedMesh>>

Same as RefFromWasmAbi::Abi

type Anchor = RcRefMut<JsGroupedMesh>

Same as RefFromWasmAbi::Anchor

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

Same as RefFromWasmAbi::ref_from_abi

impl SupportsInstanceProperty for JsGroupedMesh

impl SupportsStaticProperty for JsGroupedMesh

impl TryFromJsValue for JsGroupedMesh

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.

impl VectorFromWasmAbi for JsGroupedMesh

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