Struct PrefixMaps 

pub struct PrefixMaps {
    pub macros: PrefixMap,
    pub debug: PrefixMap,
    pub profile: PrefixMap,
}

The three answers to the question the -f*-prefix-map= family asks, which is one question asked about three kinds of output.

They are separate because gcc’s flags are separate and a build uses that: a distribution maps its debug paths to something a debugger can find the sources under and leaves __FILE__ alone, or maps __FILE__ so that an assertion message does not name a build directory and leaves the debug info pointing at the real tree. -ffile-prefix-map= is the shorthand for all three and is what a build that simply wants to be reproducible writes.

Fields

macros: PrefixMap

What __FILE__ and __BASE_FILE__ are rewritten by, from -fmacro-prefix-map=.

The only one of the three this compiler acts on today, because it is the only one whose output exists: __FILE__ is a string literal in the binary and an assertion message a user reads.

debug: PrefixMap

What a path in the debug info is rewritten by, from -fdebug-prefix-map=.

Nothing reads this yet, because no debug info is generated yet. It is kept rather than dropped so that the crate that generates it has the answer waiting rather than a flag to go and add, and crates/rucc-debug says so where the work will start.

profile: PrefixMap

What a path in the profile data is rewritten by, from -fprofile-prefix-map=.

Nothing reads this yet either, and for the same reason: there is no profile data.
