Enum Writes 

pub enum Writes {
    FromStart,
    Append,
}

How the returned handle writes.

Append is O_APPEND / FILE_APPEND_DATA: every write lands at the current end of file. That is not a convenience — it is what keeps an append-only log append-only when a writer thread and a reader disagree about the offset, and it is why this is a parameter rather than something the caller arranges with a seek.

Variants
