Trait Implementations

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

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

Formats the value using the given formatter.

impl<'vm, 'value, T> Getable<'vm, 'value> for UserdataValue<T>

where T: Userdata + Clone,

type Proxy = Variants<'value>

fn to_proxy(_vm: &'vm Thread, value: Variants<'value>) -> Result<Self::Proxy>

fn from_proxy(vm: &'vm Thread, proxy: &'value mut Self::Proxy) -> Self

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

impl<'vm, T> Pushable<'vm> for UserdataValue<T>

where T: Userdata,

fn vm_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<T> VmType for UserdataValue<T>

where T: ?Sized + VmType,

type Type = <T as VmType>::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

const EXTRA_ARGS: VmIndex = T::EXTRA_ARGS

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
