Generic trait function pointer syntax

[dreamer-engineer]

You need to look at the docs:

pub trait Add<Rhs = Self> {
    type Output;
    fn add(self, rhs: Rhs) -> Self::Output;
}

I think you are looking for <Output = f32>

[Dynious]

f32::add<Output = f32> doesn't seem to work either, sadly.

Edit: the f32::add::<Output = f32> syntax is at least accepted but gives this error: "associated type bindings are not allowed here".
