Method Generic

codersdk/toolsdk/toolsdk.go:208–226

Generic returns a type-erased version of a TypedTool where the arguments and return values are converted to/from json.RawMessage. This allows the tool to be referenced without knowing the concrete arguments or return values. The original TypedHandlerFunc is wrapped to handle type conversion.
