#![feature(coverage_attribute)]
//@ edition: 2021
//@ reference: attributes.coverage.syntax
// Demonstrates the diagnostics produced when using the syntax `#[coverage]`,
// which should not be allowed.
//
// The syntax is tested both in places that can have a coverage attribute,
// and in places that cannot have a coverage attribute, to demonstrate the
// interaction between multiple errors.
