Struct FileMeta 

#[non_exhaustive]
pub struct FileMeta {
    pub statistics: Statistics,
    pub ordering: Option<LexOrdering>,
}

Metadata fetched from a file, including statistics and ordering.

This struct is returned by FileFormat::infer_stats_and_ordering to provide all metadata in a single read, avoiding duplicate I/O operations.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

statistics: Statistics

Statistics for the file (row counts, byte sizes, column statistics).

ordering: Option<LexOrdering>

The ordering (sort order) of the file, if known.
