Struct PathStep 

pub struct PathStep {
    pub name: String,
    pub get: Rc<dyn Fn(&dyn Any) -> Box<dyn Any>>,
    pub owner: Rc<dyn Fn(&dyn Any) -> PropertyOwner>,
}

One step of a path, type-erased (one member access of upstream’s expression chain).

The steps of a path run in order: the first reads from the source of the path, each next one from the value the step before produced. get and owner take that value as &dyn Any; a value of another type is a programming error, and they panic.

Fields

name: String

The name of the property (SearchTerm).

get: Rc<dyn Fn(&dyn Any) -> Box<dyn Any>>

The value of the step, from the value of the previous one (or the source of the path).

owner: Rc<dyn Fn(&dyn Any) -> PropertyOwner>

The object that owns the property, from the value of the previous step.
