Expand description
Types supported by Parquet.
These physical types are intended to be used in combination with the encodings to control the on disk storage format. For example INT16 is not included as a type since a good encoding of INT32 would handle this.

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 Copy for Type
