This chapter provides an exhaustive list of mechanisms to pass data through the Rust GDNative binding, in both directions:
- GDScript -> Rust, e.g. to react to an input event with custom Rust logic

The goal is to serve as both an in-depth learning resource for newcomers and a reference to look up specific mechanisms at a later stage. Before delving into this chapter, make sure to read An Overview of GDNative, which explains several fundamental concepts used here.
The subchapters are intended to be read in order, but you can navigate to them directly:
