}Expand description
Bloom filter header is stored at beginning of Bloom filter data of each column and followed by its bitset.
Fields§
§num_bytes: i32The size of bitset in bytes
algorithm: BloomFilterAlgorithmThe algorithm for setting bits.
hash: BloomFilterHashThe hash function used for Bloom filter
compression: BloomFilterCompressionThe compression used in the Bloom filter

fn write_thrift_field<W: Write>( &self, writer: &mut ThriftCompactOutputProtocol<W>, field_id: i16, last_field_id: i16, ) -> Result<i16>
Used to write struct fields (which may be primitive or IDL defined types). This will
write the field marker for the given
field_id, using last_field_id to compute the
field delta used by the Thrift compact protocol. On success this will return field_id
to be used in chaining.impl Eq for BloomFilterHeader
