pub fn readable_paths<'a>(
paths: &'a [String],
unreadable: &[usize],
) -> Cow<'a, [String]>Expand description
The paths whose footers were read, out of the paths given.
A footer datui could not read is a file Polars cannot read either, and left in the scan it does not merely go unread: the first page takes the whole dataset down with it, so a directory with one file mid-write opens on an error rather than on the rows of its other files. The dataset still counts them — that is what the note is for — but the scan is over the ones that will open.
