Maybe better, but still iterating twice:
```Rust
Some(DataType::FixedSizeBinary(size)) => {
Ok(Arc::new(
FixedSizeBinaryArray::from(
[<$stat_type_prefix
FixedLenByteArrayDataPageStatsIterator>]::new($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()
.collect::<Vec<_>>()
.iter()
.map(|x| x.data())
.collect::<Vec<&[u8]>>()
)
))
},
```
