Structs

ColumnValueEncoderImpl

DataPageValues

The encoded values for a data page, with optional statistics

DictionaryPage

The encoded data for a dictionary page

Traits

ColumnValueEncoder

A generic encoder of ColumnValues to data and dictionary pages used by super::GenericColumnWriter

ColumnValues

A collection of ParquetValueType encoded by a ColumnValueEncoder

Functions

count_within_budget 🔒

How many leading values fit in byte_budget bytes, shared by the two ColumnValueEncoder::count_values_within_byte_budget* methods (one walks a contiguous slice, the other gathers by index).

create_bloom_filter 🔒

Creates a bloom filter sized for the column’s configured NDV, returning the filter and the target FPP for folding.

plain_encoded_byte_size 🔒

Plain-encoded byte cost of a single value of type T::T.

update_geo_stats_accumulator 🔒
