Cancelable tasks and object pools

• cancellable tasks
• object pools (dependent of cancellable task)

Fix #241
Fix #242

Current status: need some work to make it compile...

Main problem to consider: In my private repo api.rs I have the following code and let frb generate everything for me. However, now since it is extracted into frb itself, I need to reconsider how to write this code.

#[derive(Debug, PartialEq, Eq, Hash, Clone)]
pub struct CancelTokenHandle(pub i64, pub i64);

impl_pool_object_handle!(Arc<CancelToken>, CancelTokenHandle);

pub fn cancel_token_new(sub_pool_id: i64) -> Result<CancelTokenHandle> {
    Ok(pool::put(sub_pool_id, Arc::new(CancelToken::new())))
}

pub fn cancel_token_cancel(cancel_token: CancelTokenHandle) -> Result<()> {
    let cancel_token = pool::get_cloned(cancel_token)?;
    cancel_token.cancel();
    Ok(())
}

pub fn cancel_token_remove(cancel_token: CancelTokenHandle) -> Result<()> {
    pool::remove(cancel_token);
    Ok(())
}

@sagudev You are welcomed to make a PR to make this work :) Because I have already done the main things, and the blocking issue is #333 (comment)

I did this just to prevent stale.

Is there any chance, that cancelable tasks will be implemented in the near future?

@LowLevelSubmarine You can copy-and-paste it into your api.rs currently!
