Expand description

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

Required Methods§

source

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.
