- function names are: `sp2_` \<struct_name\> \<rust name\>. - function names are: `sp_` \<struct_name\> \<rust name\>.
- Use the rust documentation.
- Instances get consumed in the same way they do when writing rust / C# code. Do not use an instance after an (implicit!) free. - Instances get consumed in the same way they do when writing rust / C# code. Do not use an instance after an (implicit!) free.
