18//! Low-level buffer abstractions for [Apache Arrow Rust](https://docs.rs/arrow)
19//!
20//! # Byte Storage abstractions
21//! - [`MutableBuffer`]: Raw memory buffer that can be mutated and grown
22//! - [`Buffer`]: Immutable buffer that is shared across threads
23//!
24//! # Typed Abstractions
25//!
26//! There are also several wrappers over [`Buffer`] with methods for
27//! easier manipulation:
28//!
29//! - [`BooleanBuffer`][]: Bitmasks (buffer of packed bits)
30//! - [`NullBuffer`][]: Arrow null (validity) bitmaps ([`BooleanBuffer`] with extra utilities)
31//! - [`ScalarBuffer<T>`][]: Typed buffer for primitive types (e.g., `i32`, `f64`)
32//! - [`OffsetBuffer<O>`][]: Offsets used in variable-length types (e.g., strings, lists)
33//! - [`RunEndBuffer<E>`][]: Run-ends used in run-encoded encoded data
