Module types 

ZImagefile types - YAML-based image build format

This module defines all serde-deserializable types for the ZImagefile format, an alternative to Dockerfiles using YAML syntax. The format supports four mutually exclusive build modes:

1. Runtime template - shorthand like runtime: node22
2. Single-stage - base: or build: + steps: at top level
3. Multi-stage - stages: map (IndexMap for insertion order, last = output)
4. WASM - wasm: configuration for WebAssembly builds

Structs

ZCacheMount

A cache mount specification for RUN steps.

ZHealthcheck

Healthcheck configuration for the container.

ZImage

Top-level ZImagefile representation.

ZStage

A single build stage in a multi-stage ZImagefile.

ZStep

A single build instruction within a stage.

ZWasmConfig

WebAssembly build configuration for WASM mode.

Enums

ZBuildContext

Build context for building a base image from a local Dockerfile or ZImagefile.

ZCommand

A command that can be specified as either a shell string or an exec-form array of strings.

ZCopySources

Source specification for copy/add steps. Can be a single path or multiple.

ZExpose

Port exposure specification. Can be a single port or multiple port specs.

ZPortSpec

A single port specification, either a bare port number or a port with protocol suffix.
