Struct gluon_vm::api::UserdataValue

pub struct UserdataValue<T: ?Sized>(pub T);

Wrapper which extracts a Userdata value from gluon

Trait Implementations

impl<T: ?Sized> VmType for UserdataValue<T> where
    T: VmType, 

type Type = T::Type

A version of Self which implements Any allowing a TypeId to be retrieved

fn make_type(vm: &Thread) -> ArcType

Creates an gluon type which maps to Self in rust

fn make_forall_type(vm: &Thread) -> ArcType

fn extra_args() -> VmIndex

How many extra arguments a function returning this type requires. Used for abstract types which when used in return position should act like they still need more arguments before they are called

impl<'vm, T> Pushable<'vm> for UserdataValue<T> where
    T: Userdata, 

fn push(self, context: &mut ActiveThread<'vm>) -> Result<()>

Pushes self to stack. If the call is successful a single element should have been added to the stack and Ok(()) should be returned. If the call is unsuccessful Status:Error should be returned and the stack should be left intact

fn status_push(self, context: &mut ActiveThread<'vm>) -> Status where
    Self: Sized, 

unsafe fn marshal_unrooted(self, vm: &'vm Thread) -> Result<Value> where
    Self: Sized, 

fn marshal<T>(self, vm: &'vm Thread) -> Result<RootedValue<T>> where
    Self: Sized,
    T: VmRoot<'vm>, 

impl<'vm, 'value, T> Getable<'vm, 'value> for UserdataValue<T> where
    T: Userdata + Clone, 

fn from_value(vm: &'vm Thread, value: Variants<'value>) -> Self

impl<T: Debug + ?Sized> Debug for UserdataValue<T>

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

Formats the value using the given formatter.
