//! Defines public types representing Apache Arrow arrays. Arrow's specification defines
//! an array as "a sequence of values with known length all having the same type." For
//! example, the type `Int16Array` represents an Apache Arrow array of 16-bit integers.
//!
//! ```
//! extern crate arrow;
//!
//! use arrow::array::Int16Array;
//!
//! // Create a new builder with a capacity of 100
//! let mut builder = Int16Array::builder(100);
//!
//! // Append a single primitive value
//! builder.append_value(1).unwrap();
//!
//! // Append a null value
//! builder.append_null().unwrap();
//!
//! // Append a slice of primitive values
//! builder.append_slice(&[2, 3, 4]).unwrap();
//!
//! // Build the array
//! let array = builder.finish();
//!
//! assert_eq!(
//!     5,
//!     array.len(),
//!     "The array has 5 values, counting the null value"
//! );
//!
//! assert_eq!(2, array.value(2), "Get the value with index 2");
//!
//! assert_eq!(
//!     array.value_slice(3, 2),
//!     &[3, 4],
//!     "Get slice of len 2 starting at idx 3"
//! )
