Implementations

impl GetObject<'_>

pub async fn receive_bytes( &self, object_name: &str, ) -> Result<(Bytes, GetObjectResponseHeader, HeaderMap), Error>

返回：

• Vec<u8>：文件数据
• HashMap<String, String>：所有响应头

pub async fn receive_bytes_stream( &self, object_name: &str, ) -> Result<(impl Stream<Item = Result<Bytes, Error>> + use<>, GetObjectResponseHeader, HeaderMap), Error>

pub async fn download_to_file( &self, object_name: &str, file_path: &Path, ) -> Result<(GetObjectResponseHeader, HeaderMap), Error>

pub async fn generate_presigned_url( &self, object_name: &str, expires: i32, ) -> Result<String, Error>
