async-curl

This will perform curl Easy2 asynchronously for rust-lang via an Actor using tokio

How to use with multiple async request

use async_curl::{Actor, CurlActor};
use curl::easy::{Easy2, Handler, WriteError};

pub struct ResponseHandler {
    data: Vec<u8>,

    /// to the data vector.
    fn write(&mut self, data: &[u8]) -> Result<usize, WriteError> {
        self.data.extend_from_slice(data);
        Ok(data.len())
    }
}

    /// Instantiation of the ResponseHandler
    /// and initialize the data vector.
    pub fn new() -> Self {

    /// This will consumed the object and
    /// give the data to the caller
    pub fn get_data(self) -> Vec<u8> {
        self.data
