Fields§
§file_path: Option<String>
File where column data is stored. If not set, assumed to be same file as metadata. This path is relative to the current file.
file_offset: i64
Byte offset in file_path to the ColumnMetaData *
meta_data: Option<ColumnMetaData>
Column metadata for this chunk. This is the same content as what is at file_path/file_offset. Having it here has it replicated in the file metadata.
offset_index_offset: Option<i64>
File offset of ColumnChunk’s OffsetIndex *
offset_index_length: Option<i32>
Size of ColumnChunk’s OffsetIndex, in bytes *
column_index_offset: Option<i64>
File offset of ColumnChunk’s ColumnIndex *
column_index_length: Option<i32>
Size of ColumnChunk’s ColumnIndex, in bytes *
crypto_metadata: Option<ColumnCryptoMetaData>
Crypto metadata of encrypted columns *
encrypted_column_metadata: Option<Vec<u8>>
Encrypted column metadata for this chunk *
