Struct Preinclude 

pub struct Preinclude {
    pub name: String,
    pub macros_only: bool,
}

A file -imacros or -include named, read before the source file.

Design: spec/04-driver-and-cli.md section 4.4.

The flag a build reaches for when a whole tree has to see a definition that is not in any of its files. The kernel builds every object with -include of its own configuration header, and a configure script that has produced a config.h gets it into a third party source tree the same way, without a patch.

Fields

name: String

The name as it was written, which is looked for the way a quoted include is looked for.

macros_only: bool

Whether only the definitions it makes are wanted, which is what -imacros asks for.

The text of an -imacros file is read and thrown away, so a header full of declarations contributes its macros and nothing else. That is what makes it usable on a file that has already been included by the source: the definitions arrive early and the declarations do not arrive twice.
