Struct MultiFn 

pub struct MultiFn {
    pub name: Arc<str>,
    pub dispatch_fn: Value,
    pub methods: Mutex<HashMap<String, Value>>,
    pub prefers: Mutex<HashMap<String, Vec<String>>>,
    pub default_dispatch: String,
}

A Clojure multimethod — arbitrary dispatch via a user-supplied function.

Fields

pr_str(dispatch-val) → implementation fn

prefers: Mutex<HashMap<String, Vec<String>>>

recorded preferences (for future derive/hierarchy)

default_dispatch: String

normally “:default”
