Missing “Generated” status for cargo rustdoc --output-format json

[weihanglo]

Problem

For HTML format, cargo rustdoc would output a “Generated” status showing the file path

 Documenting foo v0.1.0 (/home/rust/foo)
    Finished dev [unoptimized + debuginfo] target(s) in 0.16s
   Generated /home/rust/foo/target/doc/foo/index.html

However, for --output-format json you cannot find the “Generated” status.

Steps

1. cargo new foo
2. cd foo
3. cargo +nightly rustdoc -Zunstable-options --output-format json

Possible Solution(s)

Expect there is a corresponding "Generated" status for JSON format.

For --open different formats are handled, but for "Generated" they aren't.

	compilation.root_output[&kind]
	.with_file_name("doc")
	.join(format!("{}.json", &name))
	} else {
	compilation.root_output[&kind]
	.with_file_name("doc")
	.join(&name)
	.join("index.html")
	};
