Required Methods§
Sourcefn render(&self) -> DisplayCow<'_>
fn render(&self) -> DisplayCow<'_>
A Display for a BoxedValue rendered for the user.
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
Query the value’s state
Sourcefn to_kstr(&self) -> KStringCowBase<'_>
fn to_kstr(&self) -> KStringCowBase<'_>
Interpret as a string.
Provided Methods§
Sourcefn as_object(&self) -> Option<&dyn ObjectView>
fn as_object(&self) -> Option<&dyn ObjectView>
Extracts the object value if it is a object.
Sourcefn is_nil(&self) -> bool
fn is_nil(&self) -> bool
Tests whether this value is nil
