Struct masonry::testing::Recorder

pub struct Recorder<W> { /* private fields */ }

A widget that records each time one of its methods is called.

Make one like this:

use masonry::testing::{Recording, Record, TestWidgetExt};
use masonry::testing::TestHarness;
let recording = Recording::default();
let widget = Label::new("Hello").record(&recording);

TestHarness::create(widget);
assert!(matches!(recording.next().unwrap(), Record::L(LifeCycle::WidgetAdded)));
