//! Boolean encoding utilities.
//!
//! This module provides simple boolean to string conversion functions.
//! These are lower-level utilities; the main encoding uses the `encode`
//! module's `encode_bool` and `decode_bool` functions instead.
//!
//! # Encoding
//!
//! | Value | Encoded |
//! |-------|---------|
//! | `true` | `"T"` |
//! | `false` | `"F"` |
