}Expand description
Copy is the trait that OpenDAL returns for stateful copy operations.
Required Methods§
Sourcefn next(
&mut self,
) -> impl Future<Output = Result<Option<usize>, Error>> + MaybeSend
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.
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.
