Functions

func SafeCall

func SafeCall(fn any, args ...any) (result any, err error)

SafeCall safely calls a function using reflection. It handles potential panics by recovering and returning an error. The function `fn` is expected to be a function, and `args` are the arguments to pass to that function. It returns the result of the function call (if any) and an error if one occurred during the call or if a panic was recovered.
