//! 和 罐子 的 状态 相关

use crate::identity::CanisterId;

/*

引入包后, 直接使用如下方法即可增加查询罐子状态的接口

#[ic_cdk::update]
async fn canister_status() -> ic_cdk::api::management_canister::main::CanisterStatusResponse {
    #[allow(clippy::unwrap_used)]
    ic_canister_kit::canister::status::canister_status(ic_canister_kit::identity::self_canister_id()).await.unwrap()
}

#[ic_cdk::update]
async fn canister_info(num_requested_changes: Option<u64>) -> ic_cdk::api::management_canister::main::CanisterInfoResponse {
    #[allow(clippy::unwrap_used)]
    ic_canister_kit::canister::status::canister_info(ic_canister_kit::identity::self_canister_id(), num_requested_changes).await.unwrap()
