Trait Copy 

pub trait Copy:
    Unpin
    + Send
    + Sync {
    // Required methods
    fn next(
        &mut self,
    ) -> impl Future<Output = Result<Option<usize>, 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 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", so this trait is not object safe.
