//! This crate contains the official Native Rust implementation of
//! [Apache Parquet](https://parquet.apache.org/), part of
//! the [Apache Arrow](https://arrow.apache.org/) project.
//!
//! Please see the [parquet crates.io](https://crates.io/crates/parquet)
//! page for feature flags and tips to improve performance.
//!
//! # Getting Started
//! Start with some examples:
//!
//! 1. [mod@file] for reading and writing parquet files using the
//! [ColumnReader](column::reader::ColumnReader) API.
//!
//! 2. [arrow] for reading and writing parquet files to Arrow
//! `RecordBatch`es
//!
//! 3. [arrow::async_reader] for `async` reading and writing parquet
//! files to Arrow `RecordBatch`es (requires the `async` feature).

/// Defines a an item with an experimental public API
///
/// The module will not be documented, and will only be public if the
/// experimental feature flag is enabled
///
/// Experimental components have no stability guarantees
