Struct WindowsBuildConfig 

pub struct WindowsBuildConfig {
    pub cache_dir: PathBuf,
    pub registry_auth: RegistryAuth,
    pub platform: String,
    pub os_version_override: Option<String>,
    pub scratch_size_gb: u64,
}

Configuration for the Windows builder.

Mirrors the on-disk + registry parameters required to materialise a Windows base image. Subsequent Phase 4 tasks (4.C COPY/ADD, 4.D manifest) thread additional knobs through this struct.

Fields

cache_dir: PathBuf

Build cache root. Per-build subdirectories (<cache_dir>/<build_id>/) hold the unpacked base layer chain, the working writable layer, and any future blob staging area used by 4.D/4.E.

registry_auth: RegistryAuth

Registry credentials, forwarded verbatim to the registry client when pulling the base image and (in 4.E) pushing the final manifest.

platform: String

Target OCI platform string, e.g. "windows/amd64". The registry client uses this to resolve a multi-platform index entry to a concrete manifest. Defaults to "windows/amd64" via WindowsBuildConfig::default_platform.

os_version_override: Option<String>

Optional override for the tested base image OS build (the os.version constraint, e.g. "10.0.20348.2227"). When None the platform resolver inherits the os.version reported by the pulled manifest. Used to pin a specific Windows build family when the host kernel demands an exact match.

scratch_size_gb: u64

Scratch-layer size in GiB for per-RUN ephemeral compute systems. Zero means “HCS default” (currently 20).

Implementations

impl WindowsBuildConfig

pub const fn default_platform() -> &'static str

The default target platform string: "windows/amd64". The vast majority of Windows container base images are published for this platform; windows/arm64 exists but is not in widespread use yet.

pub const fn default_scratch_size_gb() -> u64

Default scratch-layer size (20 GiB), used when WindowsBuildConfig::scratch_size_gb is zero. Matches the production HcsBackend default so behaviour is consistent across the two builders.

Trait Implementations

impl Clone for WindowsBuildConfig

fn clone(&self) -> WindowsBuildConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WindowsBuildConfig

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

Formats the value using the given formatter.
