Module focus

Module for focus-handling functionality. For details see rat-focus

Macros

• match_focus
  Does a match on the state struct of a widget. If widget_state.is_focused() is true the block is executed. There is a _ branch too, that is evaluated if none of the given widget-states has the focus.
• on_gained
  Does a match on the state struct of a widget. If widget_state.gained_focus() is true the block is executed. This requires that widget_state implements HasFocus, but that’s the basic requirement for this whole crate.
• on_lost
  Does a match on the state struct of a widget. If widget_state.lost_focus() is true the block is executed. This requires that widget_state implements HasFocus, but that’s the basic requirement for this whole crate.
