Struct AsyncFunction

pub struct AsyncFunction(/* private fields */);

Available on crate feature async and Linux only.

Implementations

impl AsyncFunction

pub fn create_async_func<'data, 'inst, 'frame, 'fut, T: Send>( ty: &FuncType, real_fn: AsyncFn<'data, 'inst, 'frame, 'fut, T>, data: *mut T, cost: u64, ) -> WasmEdgeResult<Self>

where 'data: 'fut, 'inst: 'fut, 'frame: 'fut,

Creates an async host function with the given function type.

Arguments

• ty - The types of the arguments and returns of the target function.

• real_fn - The pointer to the target function.

• data - The host context data used in this function.

• cost - The function cost in the Statistics. Pass 0 if the calculation is not needed.

Error

• If fail to create a Function, then WasmEdgeError::Func(FuncError::Create) is returned.

Trait Implementations

impl AsMut<Function> for AsyncFunction

fn as_mut(&mut self) -> &mut Function

Converts this type into a mutable reference of the (usually inferred) input type.

impl AsRef<Function> for AsyncFunction

fn as_ref(&self) -> &Function

Converts this type into a shared reference of the (usually inferred) input type.
