Type Definition arret_runtime::boxed::Captures [−][src]
type Captures = Gc<Any>;
Opaque type for a function’s captures
This has a meaning specific to the implementation of the function. This may be a dummy value
(typically Nil
) for functions that don’t capture, a single boxed value or a collection of
multiple boxed values. The only external contract is that it must be a boxed value to allow for
garbage collection.
