Enum FnBody 

pub enum FnBody {
    Ast(Vec<Stmt>),
    Compiled(Rc<dyn Any + 'static>),
}

Engine-specific representation of a function body.

• The tree-walker creates Ast bodies and re-walks the AST on every call.
• The bytecode VM creates Compiled bodies carrying a pre-compiled form (typically Rc<bop_vm::Chunk>). Rc<dyn Any> keeps bop-lang from taking a dep on any particular engine crate.

An engine that only understands one variant errors cleanly when handed the other, rather than silently misbehaving.

Variants

Ast(Vec<Stmt>)

Compiled(Rc<dyn Any + 'static>)
