# bevy_reflect_fns

Experimentation for trying out ways to support method calls using `bevy_reflect`.

This will be used together with `bevy_mod_js_scripting` to see if the design works out, and then hopefully upstreamed into `bevy_reflect`.

The core data this crates revolves around is this

```rust

pub enum PassMode {

    Ref,

    RefMut,

    Owned,

}

pub enum ReflectArg<'a> {

    Ref(&'a dyn Reflect),

    RefMut(&'a mut dyn Reflect),

    Owned(&'a dyn Reflect),

}

type RawReflectFunction =

    fn(&mut [ReflectArg<'_>]) -> Result, ReflectFunctionError>;

#[derive(Clone)]

pub struct ReflectFunction {

    pub fn_name: &'static str,

    pub signature: Vec<(PassMode, TypeId)>,

    pub f: RawReflectFunction,

}

pub struct ReflectMethods {

    methods: HashMap<&'static str, ReflectFunction>,

}

```

together with a macro to simplify creating such `ReflectFunction`s: `reflect_function!(Vec3::lerp: (Vec3, Vec3, f32))`.
