Trait DataEngine 

pub trait DataEngine: Sized {
    type Uri: ?Sized;

    // Required methods
    fn new<T: AsRef<Self::Uri>>(base_dir: T) -> EngineResult<Self>;
    fn create_bucket(
        &self,
        bucket_name: &str,
    ) -> impl Future<Output = EngineResult<()>> + Send;
    fn delete_bucket(
        &self,
        bucket_name: &str,
    ) -> impl Future<Output = EngineResult<()>> + Send;
    fn create_object(
        &self,
        bucket_name: &str,
        object_name: &str,
        data: &[u8],
    ) -> impl Future<Output = EngineResult<()>> + Send;
    fn read_object(
        &self,
        bucket_name: &str,
        object_name: &str,
    ) -> impl Future<Output = EngineResult<Vec<u8>>> + Send;
    fn delete_object(
        &self,
        bucket_name: &str,
        object_name: &str,
    ) -> impl Future<Output = EngineResult<()>> + Send;
}

此 trait 定义了 object 从何处来，所有的操作，都是幂等的

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
