Struct CursorPeek

Source 
pub struct CursorPeek<'a, 'b, T: ?Sized + ListItem<ID>, const ISNEXT: bool, const ID: u64> { /* private fields */ }
Expand description

References the element in the list next to the cursor.

§Invariants

  • ptr is an element in self.cursor.list.
  • ISNEXT == (self.ptr == self.cursor.next).
