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

Required Methods

fn run_func( &self, func: &Function, 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.

Object Safety

This trait is not object safe.
