Enum Platform 

pub enum Platform {
    MacOS,
    LinuxNative,
    LinuxNoKvm,
    Wsl2,
    Windows,
}

The execution environment for running workloads.

Variants

MacOS

macOS — Apple Virtualization.framework on 26+, Lima fallback on older

LinuxNative

Native Linux with /dev/kvm available — run Firecracker directly

LinuxNoKvm

Linux without /dev/kvm (not WSL) — requires Lima or Docker

Wsl2

WSL2 — may have KVM (Hyper-V nested virt), prefers Docker as fallback

Windows

Native Windows — Docker only (no Linux kernel)

Implementations

impl Platform

pub fn needs_lima(self) -> bool

Whether this platform needs Lima to run Firecracker. Returns false for platforms that have better alternatives (Apple VZ, Docker, native KVM).

pub fn has_kvm(self) -> bool

Whether this platform can run Firecracker directly via /dev/kvm.

pub fn supports_native_runner(self) -> bool

Whether the microvm.nix runner can execute natively (without Lima).

pub fn has_apple_containers(self) -> bool

Whether Apple Containers are available on this platform.

Requires macOS 26+ on Apple Silicon.

pub fn has_docker(self) -> bool

Whether Docker is available on this platform.

Runtime check — calls docker version to verify the daemon is running.

pub fn has_host_nix(self) -> bool

Whether Nix is available on the host and can build Linux targets.

On macOS this requires nix-daemon with a linux-builder configured. On native Linux this is always true if nix is on PATH. When true, nix build can run on the host without Lima.

pub fn is_wsl(self) -> bool

Whether this platform is WSL2.

pub fn is_windows(self) -> bool

Whether this platform is native Windows.

Trait Implementations

impl Clone for Platform

fn clone(&self) -> Platform

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Platform

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for Platform

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Platform

fn eq(&self, other: &Platform) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for Platform

impl Eq for Platform
