//! 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 {
    use ic_canister_kit::{canister::status::canister_status, identity::self_canister_id};
    let response = canister_status(self_canister_id()).await;
    ic_canister_kit::common::trap(response)
}

#[ic_cdk::update]
async fn canister_info(num_requested_changes: Option<u64>) -> ic_cdk::api::management_canister::main::CanisterInfoResponse {
    use ic_canister_kit::{canister::status::canister_info, identity::self_canister_id};
    let response = canister_info(self_canister_id(), num_requested_changes).await;
    ic_canister_kit::common::trap(response)
}
