Migrate CanisterIdRecord to ic_cdk v0.18

How do I migrate use ic_cdk::api::management_canister::main::CanisterIdRecord; with the ic_cdk v0.18?

The new module api::management_canister does not seem to expose the record.

Ah nvm, got it. Those are not needed anymore because each function is now typed with a related struct.

For example:

// Old
let result = delete_canister(CanisterIdRecord { canister_id }).await;

//
let result = delete_canister(&DeleteCanisterArgs { canister_id }).await;

Having trouble with ic_cdk::api::management_canister::http_request::HttpResponse;

cannot find where `HttpResponse` is exposed...

use of deprecated struct `ic_cdk::api::management_canister::http_request::HttpResponse`: The `api::management_canister::http_request` module is deprecated. Please use the `management_canister` module at the crate root

(nothing is here…)

and for some reason ic-cdk-bindgen(0.1.3) produces deprecated code as well :confused:

The deprecation message suggests using the ic_cdk::management_canister module.

In your case, the old HttpResponse struct you are looking for is now ic_cdk::management_canister::HttpRequestResult.

An HTTPS Outcall will then look like this:

use ic_cdk::management_canister::{HttpRequestArgs, HttpRequestResult};

async fn my_http_request(args: &HttpRequestArgs) -> HttpRequestResult {
    ic_cdk::management_canister::http_request(args)
        .await
        .unwrap()
}

Any idea what is happening with ic-cdk-bindgen? My canister uses a lot of auto generated code(because it’s using a lot of other services for which I generated bindings from candid)…

And latest bindgen just generates code which is deprecated in the latest ic-cdk release

We’ll upgrade ic-cdk-bindgen to support v0.18 as soon as possible.

In the meantime, you can manually upgrade your generated bindings to use Bounded-wait calls. The ic-cdk’s V18 upgrading guide is a good reference on how to do that.

For a more practical example, the updates made to the example.rs test asset in this PR are also a good reference.

great write up, a reference from the main README.md could be useful maybe(I couldn’t find this guide right away)

I guess I have to wait for ic-cdk-bindgen updates, there’s just no way I’m updating all those bindings I use manually(way too many). Or I need to silence the warnings until ic-cdk-bindgen is updated

Anyway, thanks for your help!
