Struct Value

pub struct Value<L: 'static> { /* private fields */ }

An abstract value type that is tracked by a cyclic garbage collector.

Call gcmodule::collect_thread_cycles to collect cycles and reclaim space.

Implementations

impl<L: Interpreter> Value<L>

pub fn new<T: AbstractValue<L> + Sized>(value: T) -> Self

Create a new Value.

pub fn downcast_ref<T: AbstractValue<L> + Sized>(&self) -> Option<&T>

Attempt to downcast.

Trait Implementations

impl<L: Clone + 'static> Clone for Value<L>

fn clone(&self) -> Value<L>

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<L: Interpreter> Display for Value<L>

fn fmt(&self, f: &mut Formatter<'_>) -> Result
