Structs

CompressedDataPage
A CompressedDataPage is compressed, encoded representation of a Parquet data page. It holds actual data and thus cloning it is expensive.
CompressedDictPage
A compressed, encoded dictionary page.
DataPage
A DataPage is an uncompressed, encoded representation of a Parquet data page. It holds actual data and thus cloning it is expensive.
DataPageHeaderV1
Data page header
DataPageHeaderV2
New page format allowing reading levels without decompressing the data Repetition and definition levels are uncompressed The remaining section containing the data is compressed if is_compressed is true
DictPage
An uncompressed, encoded dictionary page.
ParquetPageHeader

DataPageHeader
Page
A Page is an uncompressed, encoded representation of a Parquet page. It may hold actual data and thus cloning it may be expensive.
PageType

split_buffer
Splits the page buffer into 3 slices corresponding to (encoded rep levels, encoded def levels, encoded values).
split_buffer_v1
Splits the page buffer into 3 slices corresponding to (encoded rep levels, encoded def levels, encoded values) for v1 pages.
split_buffer_v2
Splits the page buffer into 3 slices corresponding to (encoded rep levels, encoded def levels, encoded values) for v2 pages.
