    = note: move occurs because `self.account_id_to_target_deadline` has type `std::collections::HashMap<u64, u64>`, which does not implement the `Copy` trait

why i am wrong? what's move do?

Sounds like you need to add mut here:

pub fn run(mut self) {

And it sounds like you need to clone account_id_to_target_deadline.

why does my pass by edit this

  let mut rx_nonce_data = self.rx_nonce_data;
        task::spawn(async move {
            while let Some(nonce_data) = rx_nonce_data.next().await {
            }
        });

but if i change self.rx_nonce_data the code will be wrong

        task::spawn(async move {
            while let Some(nonce_data) = self.rx_nonce_data.next().await {

            }
        });
