Fields§

§header_length: Option<u64>§content_length: Option<u64>§stripes: Vec<StripeInformation>§types: Vec<Type>§metadata: Vec<UserMetadataItem>§number_of_rows: Option<u64>§statistics: Vec<ColumnStatistics>§row_index_stride: Option<u32>§writer: Option<u32>

Each implementation that writes ORC files should register for a code 0 = ORC Java 1 = ORC C++ 2 = Presto 3 = Scritchley Go from https://github.com/scritchley/orc 4 = Trino

§encryption: Option<Encryption>

information about the encryption in this file

§calendar: Option<i32>§software_version: Option<String>

informative description about the version of the software that wrote the file. It is assumed to be within a given writer, so for example ORC 1.7.2 = “1.7.2”. It may include suffixes, such as “-SNAPSHOT”.
