Enum oxischeme::eval::Trampoline

pub enum Trampoline {
    Value(RootedValue),
    Thunk(RootedActivationPtr, Meaning),
}

To optimize tail calls and eliminate the stack frames that would otherwise be used by them, we trampoline thunks in a loop and encode that process in this type.

Variants

Value
Thunk
