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