Module gdnative_core::export

Functionality for user-defined types exported to the engine (native scripts).

NativeScript allows users to have their own scripts in a native language (in this case Rust). It is not the same as GDNative, the native interface to call into Godot. Symbols in this module allow registration, exporting and management of user-defined types which are wrapped in native scripts.

If you are looking for how to manage Godot core types or classes (objects), check out the core_types and object modules, respectively.

To handle initialization and shutdown of godot-rust, take a look at the init module.

For full examples, see examples in the godot-rust repository.

Modules

hint

Strongly typed property hints.

user_data

Customizable user-data wrappers.

Macros

godot_wrap_method

Convenience macro to wrap an object’s method into a Method implementor that can be passed to the engine when registering a class.

Structs

ArgBuilder

Builder for providing additional argument information for error reporting.

ArgumentError

Error during argument parsing.

ClassBuilder

Allows registration of exported properties, methods and signals.

ExportInfo

Metadata about the exported property.

IndexBounds

Defines which number of arguments is valid.

MethodBuilder

Builder type used to register a method on a NativeClass.

Property

Placeholder type for exported properties with no backing field.

PropertyBuilder

Builder type used to register a property on a NativeClass.

PropertyUsage

SignalBuilder

Class to construct a signal. Make sure to call Self::done() in the end.

SignalParam

Parameter in a signal declaration.

StaticArgs

Adapter for methods whose arguments are statically determined. If the arguments would fail to type check, the method will print the errors to Godot’s debug console and return null.

Varargs

Safe interface to a list of borrowed method arguments with a convenient API for common operations with them.

Enums

RpcMode

VarargsError

All possible errors that can occur when converting from Varargs.

Traits

Export

Trait for exportable types.

FromVarargs

Trait for structures that can be parsed from Varargs.

Method

Safe low-level trait for stateful, variadic methods that can be called on a native script type.

Mixin

Trait for mixins, manually registered #[methods] blocks that may be applied to multiple types.

NativeClass

Trait used for describing and initializing a Godot script class.

NativeClassMethods

Trait used to provide information of Godot-exposed methods of a script class.

OwnerArg

Trait for types that can be used as the owner arguments of exported methods. This trait is sealed and has no public interface.

StaticArgsMethod

Trait for methods whose argument lists are known at compile time. Not to be confused with a “static method”.

StaticallyNamed

A NativeScript “class” that is statically named. NativeClass types that implement this trait can be registered using [InitHandle::add_class].
