# Error code E0087

#### Note: this error code is no longer emitted by the compiler.

Too many type arguments were supplied for a function. For example:

    fn foo<T>() {}

    fn main() {
        foo::<f64, bool>(); // error: wrong number of type arguments:
                            //        expected 1, found 2
    }

The number of supplied arguments must exactly match the number of defined type parameters.
