Trait Copy 

pub trait Copy:
    Unpin
    + Send
    + Sync {
    // Required methods
    fn next(
        &mut self,
    ) -> impl Future<Output = Result<Option<usize>, Error>> + MaybeSend;
    fn close(
        &mut self,
    ) -> impl Future<Output = Result<Metadata, Error>> + MaybeSend;
    fn abort(&mut self) -> impl Future<Output = Result<(), Error>> + MaybeSend;
}

Copy is the trait that OpenDAL returns for stateful copy operations.

Required Methods

fn next( &mut self, ) -> impl Future<Output = Result<Option<usize>, Error>> + MaybeSend

Drive the copy operation forward.

Ok(Some(n)) means the copy operation made progress by n bytes. Ok(None) means the copy operation has completed.

fn close(&mut self) -> impl Future<Output = Result<Metadata, Error>> + MaybeSend

Close the copier and return metadata from the server-side completion response.

fn abort(&mut self) -> impl Future<Output = Result<(), Error>> + MaybeSend

Abort the pending copy operation.

Dyn Compatibility

This trait is not dyn compatible.

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