Overview of External Function Types in Gandiva +================================================= + +Gandiva supports two primary types of external functions: + +* C Functions: Functions conforming to the C calling convention. Developers can implement functions in various languages (like C++, Rust, C, or Zig) and expose them as C functions for Gandiva.
