I tried this code:

#![feature(vec_into_raw_parts)]
pub mod rs_aes;
pub mod rs_rsa;
mod utils;

use std::{borrow::Cow, error::Error};
use utils::set_panic_hook;
use wasm_bindgen::{prelude::*, JsCast};

// When the `wee_alloc` feature is enabled, use `wee_alloc` as the global
// allocator.
#[cfg(feature = "wee_alloc")]
#[global_allocator]
static ALLOC: wee_alloc::WeeAlloc = wee_alloc::WeeAlloc::INIT;

#[wasm_bindgen]
extern "C" {
  #[wasm_bindgen(js_namespace = WebAssembly,  typescript_type = "WebAssembly.Memory")]
  pub type Memory;

  #[wasm_bindgen(js_namespace = console)]
  pub fn log(s: &str);
}

#[wasm_bindgen]
pub fn shared_memory() -> Memory {
  JsValue::from(wasm_bindgen::memory()).unchecked_into::<Memory>()
}

#[wasm_bindgen]
pub enum Encode {
  BASE64,
  HEX,
}

#[wasm_bindgen]
pub struct SharedPtr {
  pub at_ptr: *mut u8,
  pub len: usize,
  pub cap: usize,
}

impl Drop for SharedPtr {
  fn drop(&mut self) {
    std::mem::drop(self);
  }
}

impl SharedPtr {
  fn new(view: Vec<u8>) -> SharedPtr {
    let (at_ptr, len, cap): (*mut u8, usize, usize) = view.into_raw_parts();
    SharedPtr { at_ptr, len, cap }
  }
}

#[wasm_bindgen]
impl SharedPtr {
  #[wasm_bindgen(catch)]
  pub fn with_capacity(capacity: usize) -> SharedPtr {
    set_panic_hook();
    let mut view: Vec<u8> = Vec::<u8>::with_capacity(capacity);
    unsafe {
      view.set_len(capacity);
    }
    SharedPtr::new(view)
  }

  #[wasm_bindgen(catch)]
  pub fn from_text(text: &str) -> SharedPtr {
    set_panic_hook();
    let view: Vec<u8> = text.as_bytes().to_vec();
    SharedPtr::new(view)
  }

  #[wasm_bindgen(catch)]
  pub fn encode(&self, encode: Encode) -> String {
    set_panic_hook();
    let view: Vec<u8> = utils::raw_from_sharedptr(self);

    match encode {
      Encode::BASE64 => utils::base64_encode(view),
      Encode::HEX => utils::hex_encode(view),
    }
  }

  #[wasm_bindgen(catch)]
  pub fn binary_to_str(&self) -> Result<String, JsValue> {
    set_panic_hook();
    let view: Vec<u8> = utils::raw_from_sharedptr(self);

    match String::from_utf8(view) {
      Ok(res) => Ok(res),
      Err(_) => Err(JsValue::NULL),
    }
  }
}

I expected to see this happen: explanation

Instead, this happened: explanation
