Trait wasmedge_sdk::Engine

pub trait Engine {
    fn run_func(
        &self,
        func: &Func,
        params: impl IntoIterator<Item = WasmValue>
    ) -> WasmEdgeResult<Vec<WasmValue>>;

}

The object that is used to perform a host function is required to implement this trait.

Required Methods

fn run_func(
    &self,
    func: &Func,
    params: impl IntoIterator<Item = WasmValue>
) -> WasmEdgeResult<Vec<WasmValue>>

Runs a host function instance and returns the results.

Arguments

• func - The function instance to run.

• params - The arguments to pass to the function.

Errors

If fail to run the host function, then an error is returned.

fn run_func_ref(
    &self,
    func_ref: &FuncRef,
    params: impl IntoIterator<Item = WasmValue>
) -> WasmEdgeResult<Vec<WasmValue>>

Runs a host function instance by calling its reference and returns the results.

Arguments

• func_ref - A reference to the target host function instance.

• params - The arguments to pass to the function.

Errors

If fail to run the host function, then an error is returned.
