Crate abi_vtable_macro 

abi-vtable-macro — shadow-mode vtable generation

Shadow mode: annotate a trait and every companion entity of the abi-mode protocol is generated automatically — no manual steps. Usage is as frictionless as the native (dyn) mode.

When to use which mode

• Rust-only → native (dyn) mode: fastest and lightest, direct fat pointers, Arc ref-counting, no vtable struct at all.
• Cross-language (C/C++/Zig/…) → this (abi) mode: the generated #[repr(C)] vtable is the language-neutral contract.
