Function find
fn find(arch_or_target: &str, tool: &str) -> Option<std::process::Command>Attempts to find a tool within an MSVC installation using the Windows registry as a point to search from.
The arch_or_target argument is the architecture or the Rust target name
that the tool should work for (e.g. compile or link for). The supported
architecture names are:
"x64"or"x86_64""arm64"or"aarch64""arm64ec""x86","i586"or"i686""arm"or"thumbv7a"
The tool argument is the tool to find. Supported tools include:
- MSVC tools:
cl.exe,link.exe,lib.exe, etc. MSBuild:msbuild.exe- Visual Studio IDE:
devenv.exe - Clang/LLVM tools:
clang.exe,clang++.exe,clang-*.exe,llvm-*.exe,lld.exe, etc.
This function will return None if the tool could not be found, or it will
return Some(cmd) which represents a command that's ready to execute the
tool with the appropriate environment variables set.
Note that this function always returns None for non-MSVC targets (if a
full target name was specified).
