#![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.
