e031: FFI Deep Dive

Exposing Rust types and functions to C API consumers.

Show Notes

It’s impossible to make the declarations below follow the order I talked through them on the recording without also making them horrible to read, so just use this outline instead:

1. add_in_rust
2. Strings
   1. concat_strings
   2. free_rust_string
3. Point
   1. point_translate
4. union
5. OpaquePoint
   1. opaque_point_new
   2. opaque_point_translate
   3. opaque_point_free
