Struct SafeArrayBuffer

pub struct SafeArrayBuffer { /* private fields */ }

Rust representation of Nodejs ArrayBuffer In regular cases can be used ArrayBuffer and it will be more effective. But in the case of usage node_bindgen in electron context, ArrayBuffer will not work because of restrictions from electron side. SafeArrayBuffer can be used as an effective workaround. Theoretically, usage of SafeArrayBuffer might give a very small performance degradation compared to ArrayBuffer, but it can be ignored in most cases.

Examples

use node_bindgen::derive::node_bindgen;
use node_bindgen::core::{buffer::JSArrayBuffer, safebuffer::{SafeArrayBuffer}};

#[node_bindgen]
fn msg_from_js(data: JSArrayBuffer) -> Result<String, NjError> {
  let message = String::from_utf8(data.to_vec())?;
   Ok(format!("reply {}", message))
}
#[node_bindgen]
fn msg_to_js() -> Result<SafeArrayBuffer, NjError> {
  let message = String::from("Hello from Rust!");
  Ok(SafeArrayBuffer::new(message.to_vec()))
}
