//! Functions to calculate names for FFI symbols
//!
//! All of these functions input a `namespace` parameter which is:
//! - The UDL namespace for UDL-based generation
//! - The "module path" of the item for proc-macro based generation. Right now this is actually just the
//! crate name, but we eventually hope to make this the full module path.
//!
//! This could cause collisions in the case where you combine UDL and proc-macro generation and you
//! set the UDL namespace to the name of another crate. This seems so pathological that it's not
//! worth the code complexity to prevent it.
