Enum Arch 

pub enum Arch {
    X86_64,
    I386,
    Aarch64,
}

The architecture of the program a process runs, which is that of its main executable.

Wine itself, the unix side with ntdll.so and this library, is built for arm64 and runs natively; x86 code is emulated inside the process.

Variants

X86_64

A 64-bit x86 program. It runs in an ARM64EC process with its x86 code emulated.

I386

A 32-bit x86 program, run through wow64 with its x86 code emulated.

Aarch64

A native ARM64 program.

Implementations

impl Arch

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

The <arch>-windows builtin directory name. The builtins of an x86_64 process load from aarch64-windows, as upstream Wine does on an arm64 host: they are ARM64X modules that serve the process’s ARM64EC side.

pub const fn of_process(wow64: bool, machine: Option<u16>) -> Self

The arch of the current process. wow64 says whether it is a wow64 (32-bit) process; machine is the Machine field of its main image’s COFF header, when it could be read.

The bundle only runs x86 programs under wow64, so a wow64 process is i386. A 64-bit process is always native from Wine’s side (ARM64EC for an x86_64 program), so the main image decides: IMAGE_FILE_MACHINE_ARM64 is a native ARM64 program, and anything else, an unreadable header included, counts as x86_64. An ARM64EC executable carries the AMD64 machine in its header and so also counts as x86_64, which is what it presents itself as.
