Enum Chip 

pub enum Chip {
    X86,
    X64,
    Arm,
    Arm64,
}

The architectures Microsoft ships a CRT for, spelled the way each document spells them.

Two spellings, because the package ids and the SDK installer names disagree about case and about arm64. That is not a thing to normalise away: both are keys into somebody else’s document and a key is what it is.

Variants

X86

32-bit x86.

X64

x86-64.

Arm

32-bit ARM.

Arm64

64-bit ARM.

Implementations

impl Chip

pub const fn of(target: TargetTuple) -> Option<Self>

Which chip a target is, or None for a target Microsoft ships nothing for.

ARM64EC has no answer here on purpose. It is tier 4 in spec/cross-compile/04-target-matrix.md, nothing in this compiler emits code for it, and the manifest’s ARM64EC packages are a few kilobytes of thunks rather than a C library.

pub const fn in_package(self) -> &'static str

How a Visual C++ package id spells it.

pub const fn in_installer(self) -> &'static str

How a Windows SDK installer name spells it.

pub const fn in_tree(self) -> &'static str

How the tree --sysroot reads spells it in a directory name.

LLVM’s names rather than Microsoft’s, because that is what xwin produces and the tree is the one it produces. So a target that was fetched with xwin and one that was fetched with this both answer to the same --sysroot, and the x64 in Microsoft’s own package names stays in the packages where a person reading a manifest would go looking for it.
