Struct gluon_vm::api::FutureResult

pub struct FutureResult<F>(pub F);

Wrapper around a Future which can be used as a return value to let the virtual machine know that it must resolve the Future to receive the value.

Methods

impl<F> FutureResult<F>

pub fn new<'vm>(f: F) -> Self where
    F: Future<Error = Error> + Send + 'static,
    F::Item: Pushable<'vm>, 

Trait Implementations

impl<F> VmType for FutureResult<F> where
    F: Future,
    F::Item: VmType, 

type Type = <F::Item 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 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

fn make_forall_type(vm: &Thread) -> ArcType

impl<'vm, F> AsyncPushable<'vm> for FutureResult<F> where
    F: Future<Error = Error> + Send + 'static,
    F::Item: Pushable<'vm>, 

fn async_push(
    self,
    context: &mut ActiveThread<'vm>,
    frame_index: VmIndex
) -> Result<Async<()>>

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 async_status_push(
    self,
    context: &mut ActiveThread<'vm>,
    frame_index: VmIndex
) -> Status where
    Self: Sized,
