Module parquet::file

Main entrypoint for working with Parquet API. Provides access to file and row group readers, record API, etc.

See reader::SerializedFileReader for a starting reference, metadata::ParquetMetaData for file metadata, and statistics for working with statistics.

Example

use std::fs::File;
use std::path::Path;
use parquet::file::reader::{FileReader, SerializedFileReader};

let path = Path::new("data/alltypes_plain.parquet");
let file = File::open(&path).unwrap();
let reader = SerializedFileReader::new(file).unwrap();

let parquet_metadata = reader.metadata();
assert_eq!(parquet_metadata.num_row_groups(), 1);

let row_group_reader = reader.get_row_group(0).unwrap();
assert_eq!(row_group_reader.num_columns(), 11);
