Trait ScopeVar 

pub trait ScopeVar:
    Any
    + Send
    + Sync {
    // Required methods
    fn as_any(&self) -> &dyn Any;
    fn as_any_mut(&mut self) -> &mut dyn Any;
    fn clone_box(&self) -> Box<dyn ScopeVar>;
}

This traits defines variables that can be stored inside of an execution’s Scope.

Required Methods

fn as_any(&self) -> &dyn Any

fn as_any_mut(&mut self) -> &mut dyn Any

fn clone_box(&self) -> Box<dyn ScopeVar>

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
