Struct Machine 

pub struct Machine {
    pub host: Option<Triple>,
    pub sysroot: Option<PathBuf>,
    pub sdk: Option<PathBuf>,
    pub include: Option<String>,
}

What the machine says about itself, and what the command line said over the top of it.

Separated from the lookup so that the lookup is a function of its arguments and can be tested for a platform the test is not running on. Everything here is read once, in system_dirs, which is the only place that talks to the environment.

Fields

host: Option<Triple>

The triple of the machine the compiler is running on, when it is one we know.

sysroot: Option<PathBuf>

--sysroot, which prefixes the configured directories, or -isysroot, which is the spelling Apple’s tools use and which means the same thing to us.

sdk: Option<PathBuf>

The SDK to compile against on an Apple platform, once it has been found.

include: Option<String>

INCLUDE, which is how every Windows toolchain says where its headers are. The entries are separated by ;, which is a path separator there and a legal character in a file name nowhere.
