Passing Type Variables to Functions for Type Assertions
You want to perform type assertions by passing a type into a function. Essentially, you aim to achieve the following:
<code class="go">// Note that this is pseudocode, because Type isn't valid here func myfunction(mystring string, mytype Type) { ... someInterface := translate(mystring) object, ok := someInterface.(mytype) ... // Do other stuff } func main() { // Desired function call myfunction("hello world", map[string]string) }</code>
To successfully perform type assertions in myfunction, use the following function declaration:
<code class="go">package main import "reflect" func myfunction(v interface{}, mytype interface{}) bool { return reflect.TypeOf(v) == reflect.TypeOf(mytype) } func main() { assertNoMatch := myfunction("hello world", map[string]string{}) fmt.Printf("%+v\n", assertNoMatch) // false assertMatch := myfunction("hello world", "stringSample") fmt.Printf("%+v\n", assertMatch) // true }</code>
This approach involves using a sample of the type you want to match, ensuring that the types are identical for successful type assertion.
