1//! Token 2022 (Token Extensions) program instruction decoder.
2//!
3//! This module provides a macro-derived decoder for the Token 2022 program,
4//! which uses single-byte discriminators based on variant indices.

11/// Token 2022 program instructions.
12///
13/// The Token 2022 program uses a 1-byte discriminator (variant index).
14/// Each variant's discriminator is its position in this enum (0, 1, 2, ...).
15///
16/// Token 2022 is a superset of SPL Token (indices 0-24 are compatible).
17/// Indices 25+ are Token Extensions specific instructions.
18///
19/// Note: Complex types (Pubkey, COption<Pubkey>, Vec<ExtensionType>) are not
20/// fully parsed; only primitive fields are extracted.
