Struct AsyncGuestCall 

pub struct AsyncGuestCall<'c, D: Send + 'static, C> { /* private fields */ }

A guest call to a WASM component function, which may be executed asynchronously.

It’s expected that the call_async method will be called to execute the function call in all cases, unless an error occurs during the setup of the call.

Implementations

impl<'c, D: Send, C> AsyncGuestCall<'c, D, C>

pub async fn call_async(self) -> Result<AsyncGuestResult<'c, D, C>, Error>

Calls the underlying WASM component function with the provided arguments and results.

Returns an error if the function call fails, or an AsyncGuestResult containing the results of the call.

Methods from Deref<Target = GuestCallData<'c, D, C>>

pub fn store(&self) -> StoreContext<'_, D>

Returns the WASM runtime store context.

pub fn store_mut(&mut self) -> StoreContextMut<'_, D>

Returns a mutable reference to the WASM runtime store context.

pub fn context(&mut self) -> &C

Returns the custom trampoline-specific context.

pub fn interface(&self) -> &ForeignInterfacePath

Returns the fully-qualified WIT foreign interface path of the function being called.

pub fn method(&self) -> &str

Returns the method name of the function being called.

pub fn func_type(&self) -> &FuncType

Returns the type signature of the function being called.

pub fn arguments(&self) -> &[Val]

Provides an immutable reference to the input arguments of the function call.

Trait Implementations
