//! BACnet protocol types per ASHRAE 135-2020.
//!
//! This crate provides the foundational types for the BACnet protocol:
//! enumerations, primitive data types, addresses, and error types.
//!
//! It has zero runtime dependencies beyond `bitflags` and `thiserror`,
//! and supports `no_std` environments via the `std` feature flag.

#![cfg_attr(not(feature = "std"), no_std)]

#[cfg(not(feature = "std"))]

/// 3 bytes (SC VMAC), or 18 bytes (BIP6 IP:port). SmallVec avoids
/// heap allocation for the common cases.
