zirv-config

zirv-config is an expandable configuration library for Rust backend applications. It provides a global, mutable configuration store that aggregates settings from multiple subsystems (e.g. server, logging, etc.). Developers can register configuration blocks under namespaces, and later retrieve or update the configuration using convenient macros.

Features

• Global Configuration Store:
  The configuration is maintained as a JSON object in a global store. This store is expandable—subsystems can register their configuration data under a unique namespace.

• Environment Integration:
  Automatically loads environment variables (and optionally a .env file via dotenvy) to initialize configuration values.

• Dynamic Registration:
  Easily register new configuration blocks using the register_config! macro.

• Flexible Access:
  Retrieve the entire configuration or a specific configuration value by using dot-separated keys with the read_config! macro.

• Runtime Updates:
  Update configuration values at runtime using the write_config! macro.

Installation

Add zirv-config as a dependency in your project's Cargo.toml:

cargo add zirv-config
