Struct rune::runtime::Future

pub struct Future { /* private fields */ }

A type-erased future that can only be unsafely polled in combination with the virtual machine that created it.

Implementations

impl Future

pub fn new<T, O>(future: T) -> Result<Self>

where T: 'static + Future<Output = VmResult<O>>, O: ToValue,

Construct a new wrapped future.

pub fn is_completed(&self) -> bool

Check if future is completed.

This will prevent it from being used in a select expression.

Trait Implementations

impl Debug for Future

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

Formats the value using the given formatter.

impl FromValue for Future

fn from_value(value: Value) -> VmResult<Self>

Try to convert to the given type, from the given value.

impl Future for Future

type Output = VmResult<Value>

The type of value produced on completion.

fn poll(self: Pin<&mut Self>, cx: &mut Context<'_>) -> Poll<VmResult<Value>>

Attempt to resolve the future to a final value, registering the current task for wakeup if the value is not yet available.

impl InstallWith for Future

fn install_with(module: &mut Module) -> Result<(), ContextError>

Hook to install more things into the module.

impl MaybeTypeOf for Future

fn maybe_type_of() -> Option<FullTypeOf>

Type information for the given type.

impl Named for Future

const BASE_NAME: RawStr = _

impl ToValue for Future

fn to_value(self) -> VmResult<Value>

Convert into a value.

impl TryFrom<Future> for Value

type Error = Error
