Enum CopyDest 

pub enum CopyDest {
    At(u64),
    Append,
}

Where a copy’s bytes land in the destination.

Not a bare offset: an append-mode handle has no offset to name — both backends refuse a positional write on one, and the position is chosen by the platform at write time — yet copying to the current position of such a handle is perfectly meaningful.

Variants

At(u64)

At an absolute offset.

Append

Through File::append, which places bytes at the end of a handle opened for appending. Like append itself, this belongs to such a handle: on any other one it writes wherever the platform’s own position happens to be.
