//! 和 罐子 的 状态 相关

use super::types::{CanisterInfoArgs, CanisterInfoResult, CanisterStatusArgs, CanisterStatusResult};

/*

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_canister_kit::types::CanisterStatusResult {
    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_canister_kit::types::CanisterInfoResult {
    use ic_canister_kit::{canister::status::canister_info, identity::self_canister_id};
    let response = canister_info(self_canister_id(), num_requested_changes).await;
