Struct Dumps 

pub struct Dumps {
    pub macros: bool,
}

What the -d family asks to be dumped alongside, or instead of, the preprocessed output.

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

GCC spells these as letters packed into one flag, so -dDI is two of them, and a letter it does not know is ignored rather than rejected. That last part is deliberate on GCC’s side and worth copying: the family is a debugging aid and a build that passes -dumpbase should not die on the -d.

Fields

macros: bool

-dM. Print the macros that are defined at the end, and nothing else.

Implementations

impl Dumps

pub fn is_family(arg: &str) -> bool

Whether arg is a flag from this family rather than something else beginning with -d.

The check is here rather than in the driver so that the set of letters and the set of flags accepted cannot drift apart. It matters because -dumpversion also begins with -d, and a family that swallowed every such flag would turn a flag we have not written into a dump of nothing.

pub fn add(&mut self, letters: &str)

Reads the letters after -d, ignoring the ones we do not implement yet.

pub const fn any(self) -> bool

Whether anything at all was asked for.
