//! Types that represent [core types](https://docs.godotengine.org/en/stable/development/cpp/core_types.html) of Godot.
//!
//! In contrast to generated Godot class types from the `api` module, the types in here are hand-written in idiomatic Rust and
//! are the counterparts to built-in types in GDScript.
//!
//! godot-rust provides optional serialization support for many core types.  Enable the feature `serde` to make use of it.
