orion-variate-engineering

What problem does it solve?

It helps engineers accurately model configuration values and environment placeholders for the Rust crate orion-variate, avoiding mistakes in parsing, evaluation order, mutability, and migration from older APIs.

Core Features & Use Cases

• Value and dictionary modeling: Build nested data using ValueType (including objects, lists, and typed scalars) and manage case-insensitive access via ValueDict/EnvDict.
• Deterministic environment placeholder expansion: Render ${VAR} and ${VAR:default} templates with correct precedence (EnvDict first, then system env, then default, otherwise unchanged placeholders) and validation via needs_env_eval/list_env_vars.
• Mutability- and origin-aware variable handling: Define variables with VarDefinition and VarCollection across Immutable/System/Module mutability groups, including safe merge behavior and origin-aware overwrites using OriginDict/OriginValue.

Quick Start

Ask for a source-accurate migration or implementation plan by saying: "Using orion-variate-engineering, show me the correct ValueType and ValueDict setup for ${VAR:default} environment interpolation and the VarCollection/OriginDict merge rules for my mutability model."
