Number Slices: `[u8]`, `[i8]`, `[u16]`, `[i16]`, `[u32]`, `[i32]`, `[u64]`, `[i64]`, `[f32]`, and `[f64]`

`T` parameter	`&T` parameter	`&mut T` parameter	`T` return value	`Option<&T>` parameter	`Option<T>` return value	JavaScript representation
No	Yes	Yes	No	No	No	A JavaScript `TypedArray` view of the Wasm memory for the boxed slice of the appropriate type (`Int32Array`, `Uint8Array`, etc)

Example Rust Usage


# #![allow(unused_variables)]
#fn main() {
use wasm_bindgen::prelude::*;

#[wasm_bindgen]
pub fn take_number_slice_by_shared_ref(x: &[f64]) {}

#[wasm_bindgen]
pub fn take_number_slice_by_exclusive_ref(x: &mut [u8]) {}

#}

Example JavaScript Usage

import {
  take_number_slice_by_shared_ref,
  take_number_slice_by_exclusive_ref,
} from './guide_supported_types_examples';

take_number_slice_by_shared_ref(new Float64Array(100));
take_number_slice_by_exclusive_ref(new Uint8Array(100));
