fn conflict_copy(
path: &Path,
here: &str,
known: Option<&Known>,
now_ms: i64,
) -> Result<PathBuf, String>Expand description
A file two devices changed, copied beside it before the other’s version
takes its place, under conflict_name: dated by when the version it holds
was made, so that every device holding that version names it alike and one
copy travels, not one each. Returns where it is.
