Trait gut::mesh::attrib::AttribPromote

pub trait AttribPromote<SI, TI> where
    SI: AttribIndex<Self>,
    TI: AttribIndex<Self>, {
    fn attrib_promote<U, F>(
        &mut self, 
        name: &'a str, 
        combine: F
    ) -> Result<&Attribute<TI>, Error>
    where
        U: 'static + Clone,
        F: for<'b> FnMut(&'b mut U, &'b U);
}

Promote attributes from one topology to another.

Required methods

fn attrib_promote<U, F>(
    &mut self,
    name: &'a str,
    combine: F
) -> Result<&Attribute<TI>, Error> where
    U: 'static + Clone,
    F: for<'b> FnMut(&'b mut U, &'b U), 

Promote the given attribute from source topology SI to target topology TI.

A mutable reference to the resulting attribute is returned upon success.

Collisions are handled using the given combine closure which takes two attribute components of type T and combines them into a single T to be written to the target topology attribute.

If an attribute with the same name already exists at the target topology, it will be combined with the promoted attribute. If that attribute has the wrong type, an error is returned.
