pub fn recording<T>(f: impl FnOnce() -> T) -> (T, BTreeSet<String>)Expand description
What f gives, and the paths Bundle::bytes found while it ran on
this thread (also through Bundle::file and the formats that read a
bundle). Unlike watch, it is scoped, and more than one tool can use
it at once. Nested, the outer call sees the inner one’s reads too.
Bundle::has records nothing.
