3///
4/// compat is a boundary layer for the public API.
5///
6/// It lets sdk expose either the legacy compatibility types or the current
7/// Solana 3.0 types at the API surface, while keeping the implementation itself
8/// always on Solana 3.0.
9///
10/// In practice, compat::{Pubkey, borsh, ...} is used only for public function
11/// parameters and return types. As soon as execution enters a function body, inputs
12/// are normalized to the Solana 3.0 types. with the help of AsModern and Modern traits
13/// and the internal logic runs entirely on Solana 3.0. If a value needs to cross
14/// back out through the public API, it is converted back at the boundary with the help
15/// of Compat trait.
