[][src]Function syntax::mut_visit::visit_clobber

pub fn visit_clobber<T, F>(t: &mut T, f: F) where
    F: FnOnce(T) -> T, 

Use a map-style function (FnOnce(T) -> T) to overwrite a &mut T. Useful when using a flat_map_* or filter_map_* method within a visit_ method. Abort the program if the closure panics.
