Struct ReflectMessageFns 

pub struct ReflectMessageFns {
    pub write_message: fn(&mut World, &(dyn PartialReflect + 'static), &TypeRegistry),
}

The raw function pointers needed to make up a ReflectMessage.

This is used when creating custom implementations of ReflectMessage with ReflectMessage::new().

Note: Creating custom implementations of ReflectMessage is an advanced feature that most users will not need. Usually a ReflectMessage is created for a type by deriving [Reflect] and adding the #[reflect(Message)] attribute. After adding the event to the [TypeRegistry], its ReflectMessage can then be retrieved when needed.

Creating a custom ReflectMessage may be useful if you need to create new message types at runtime, for example, for scripting implementations.

By creating a custom ReflectMessage and inserting it into a type’s [TypeRegistration][bevy_reflect::TypeRegistration], you can modify the way that reflected messages of that type will be written to the Bevy world.

Fields

write_message: fn(&mut World, &(dyn PartialReflect + 'static), &TypeRegistry)

Function pointer implementing ReflectMessage::write_message.

Implementations

impl ReflectMessageFns

pub fn new<M>() -> ReflectMessageFns

where M: Message + FromReflect + TypePath,

Get the default set of ReflectMessageFns for a specific event type using its [FromType] implementation.

This is useful if you want to start with the default implementation before overriding some of the functions to create a custom implementation.

Trait Implementations

impl Clone for ReflectMessageFns

fn clone(&self) -> ReflectMessageFns

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
