Struct Value

Source

pub struct Value<T>where
    T: Clone,
{ /* private fields */ }

Expand description

Helper to move values to/from callback

#Example

  let value = gemgui::Value::new(String::from(""));
  let assign = {
    let value = value.clone();
       |ui_ref: UiRef| async move { 
       let txt = ui_ref.element("content").html().await.unwrap();
        value.assign(txt);
        }
 };
 ui.on_start_async(assign);
 /// later on...   
 assert_eq!("Lorem ipsum, vino veritas", value.cloned().as_str().trim());
