代码示例无法运行

cargo --version
cargo 1.60.0 (d1fd9fe 2022-03-01)

Cargo.toml

qiniu-sdk = { version = "0.1.0", features = ["utils", "etag", "credential", "upload-token", "http", "http-client", "apis", "objects", "upload", "async", "reqwest", "isahc", "ureq", "c_ares", "trust_dns", "dns-over-tls", "dns-over-https", "trust_dns", "c_ares"] }

这是我的代码，从复制 README 中复制的

use qiniu_sdk::upload_token::{UploadPolicy, credential::Credential, prelude::*};
use std::time::Duration;

let credential = Credential::new(access_key, secret_key);
let upload_token = UploadPolicy::new_for_bucket(bucket_name, Duration::from_secs(3600)).build_token(credential, Default::default())?;
println!("{}", upload_token);

这是cargo check的结果
