psychedelic / ic-kit Goto Github PK

It would be really helpful if you could document how to do the following with ic-kit:

• dynamic canister creation
• automatic Candid generation
• inter canister calls

as comments in the examples provided and provide any guidance on how to set it up from scratch on a new project.

I was using ic-kit 0.4.8 before. It included calls to the management canister as documented here for the dynamic creations of canisters but that seems to have been removed in v0.5 onwards.

And I had been using the cargo test mechanism of automatic Candid generation as used in some other Psychedelic projects like this

For inter canister calls, I tried the mechanism outlined here but it's not type safe so it breaks compilation with Cargo. I created a post for it here

I feel ic-kit 0.5 would probably solve all of the above but I'm unable to make it work atm.

I see some of the examples have pending todos and I imagine you'll be fleshing them out in more details.

In case you already plan to cover the above, please ignore this issue :)

I see that there is something interesting with cycles going on, but I can't quite put my finger on it. Could you elaborate on it, please?

Hi. Amazing library! Can you please provide some insight on how to mock a canister with existing methods.

Say, I have a method

#[update]
async fn do_nothing(my_arg: u64) -> Result<(), String> {
    Ok(())
}

How would I create a Canister mock with the method above? I've tried to use RawHandler, but cannot figure out how to transfer arguments correctly.

The way I want to use it later is like so:

let canister = Canister::new(mock_principals::alice())
    .method("do_nothing", ...);

let ctx = canister.context().inject();
ic::call_with_payment(mock_principals::alice(), "do_nothing", (1000), 100);

Is it even possible with the current implementation?

I found that ic_cdk 0.4.0 deprecate block_on function and use its own spawn.

ic_kit use ic_cdk::block_on to do the job of ic::spwan.

Besides, ic_cdk::spawn doesn't need Send trait bound to the future F while ic_kit does.

#[inline(always)]
pub fn spawn<F: 'static + std::future::Future<Output = ()> + std::marker::Send>(future: F) {
    get_context().spawn(future)
}

When I have a job which call another canister, the future returned does not have Send trait. Thus ic::spawn can not execute the job.
