e031: FFI Deep Dive

Exposing Rust types and functions to C API consumers.

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:

add_in_rust
Strings

concat_strings
free_rust_string

Point

point_translate

union
OpaquePoint

opaque_point_new
opaque_point_translate
opaque_point_free
