pub fn compression_supported(
    format: FormatType,
    compression: CompressionType,
) -> bool
Expand description

Whether format actually encodes compression on write.

Only Parquet has a compression encoder (see crate::format::parquet); the CSV writer (crate::format::csv) ignores the codec entirely. Accepting a non-None codec for CSV would be a silent no-op — the file stays uncompressed while the run manifest records the codec — so config validation rejects that combination up-front (Finding #10). None is always supported (it means “do not compress”).
