Initial problem : I tried to export to wasm different complex structures. Time benchmarks were strange and in linear time for every structure.

So I tried to export vectors of numbers

Exporting a vector of 6

extern crate wasm_bindgen;
extern crate js_sys;

use wasm_bindgen::prelude::*;

use std::collections::BTreeSet;

#[wasm_bindgen]
pub struct IntVector {
    values: Vec<i32>
