So: ```Rust Some(DataType::FixedSizeBinary(size)) => { Ok(Arc::new( FixedSizeBinaryArray::try_from_iter( [<$stat_type_prefix FixedLenByteArrayDataPageStatsIterator>]::new($iterator).map(|x| { x.into_iter().filter_map(|x| x.and_then(|x| { if x.len().try_into() == Ok(*size) { Some(x) } else { log::debug!( "FixedSizeBinary({}) statistics is a binary of size {}, ignoring it.", size, x.len(), ); None } })) }) .flatten() ).unwrap_or_else(|_| { FixedSizeBinaryArray::new(*size, vec![].into(), None) }) )) }, ``` -- This is an automated message from the Apache Git Service.
