Bevy Reflection on Steroids
A series of supplementary extensions to the
bevy_reflect
crate that powers aspects of the
Bevy game engine.
bevy_reflect
provides is a general reflection framework for Rust structs, with
rudimentary support for traits.
Highlights
- Integrates seamlessly with
bevy_reflect
. - Includes a facility to register types globally without explicitly calling
TypeRegistry::register()
. This feature is gated behind the "inventory" crate feature, enabled by default. See [enable_global_type_registration
]. - Includes a facility to perform generic dynamic casts between trait objects,
patching a hole in the Rust language (similar to C++
dynamic_cast
). See the [Cast
] trait. - Includes the equivalent of
downcast-rs
, but using theReflect
trait instead ofAny
. See [DowncastReflect
]. - Serialization and deserialization of opaque trait objects (similar to
typetag
).
This crate provides a much more intuitive and user-friendly way of interacting with reflected types through arbitrary trait objects.
By implementing [DynamicTrait
] for dyn MyTrait
, reflection is made available
to all dynamic trait object references of that type. The only requirements are
that the trait has [DowncastReflect
] as a supertrait, and that a call to the
macro impl_dynamic_trait!(MyTrait, ReflectMyTrait)
is
present in the code.
