Required Methods§
sourcefn render(&self) -> DisplayCow<'_>
fn render(&self) -> DisplayCow<'_>

sourcefn source(&self) -> DisplayCow<'_>
fn source(&self) -> DisplayCow<'_>
A Display for a Value as source code.
sourcefn query_state(&self, state: State) -> bool
fn query_state(&self, state: State) -> bool

Provided Methods§
sourcefn as_object(&self) -> Option<&dyn ObjectView>
fn as_object(&self) -> Option<&dyn ObjectView>
