Struct BuildContext 

pub struct BuildContext {
    pub context_dir: PathBuf,
    pub dockerfile_path: PathBuf,
    pub build_args: HashMap<String, String>,
    pub tag: String,
    pub ltsc: Option<String>,
}

Inputs to a single build.

One BuildContext per WindowsBuilder::build_skeleton invocation; holds the on-disk paths the parser reads (Dockerfile + COPY sources) plus the build-time ARG values and the final image tag.

Fields

context_dir: PathBuf

Path to the build root. Everything COPY/ADD reads is resolved relative to this directory; the Dockerfile lives here unless dockerfile_path gives an absolute path.

dockerfile_path: PathBuf

Path to the Dockerfile, either relative to context_dir or absolute. The skeleton uses Dockerfile::parse on the file’s contents.

build_args: HashMap<String, String>

Build-time variables (--build-arg KEY=VALUE). Stored verbatim and applied during Dockerfile variable expansion in later tasks.

tag: String

Final image tag, e.g. "myapp:latest". Recorded for 4.D’s manifest emission and 4.E’s push; the 4.A skeleton holds it but does not act on it.

ltsc: Option<String>

Windows LTSC line to target for FROM image rewrites (e.g. "ltsc2022", "ltsc2025"). When set, the parsed Dockerfile FROM reference is run through crate::windows_image_resolver::rewrite_image_for_windows so a generic Docker Hub reference (ubuntu:24.04, golang:1.24, etc.) is replaced with the equivalent prebuilt Windows image under ghcr.io/blackleafdigital/zlayer/.... None means the builder uses its default (ltsc2022).
