Macro program_dispatch 

macro_rules! program_dispatch {
    ($program_mod:ident) => { ... };
}

Generate the small runtime bridge for a #[program(entrypoint = false)] module.

New programs do not need this macro: #[program] emits the same audited Hopper entrypoint bridge automatically. Keep program_dispatch! for compatibility and for unusual crates that intentionally disable the automatic bridge.

#[program(entrypoint = false)]
mod counter_program {
    // handlers
}

hopper::program_dispatch!(counter_program);
