You can load LiteLLM-RS configuration by parsing a YAML file and applying environment variable substitution, such as replacing ${JWT_SECRET} with runtime values. This process uses type-safe Rust models to ensure your gateway settings are parsed and validated correctly.

Hot-reloading gateway configuration works by applying runtime updates to your YAML settings without downtime. It utilizes a validation pipeline with defaults and error handling to ensure that only type-safe and valid configurations are applied to the running system.

The best way to validate type-safe Rust models from YAML is to pass the parsed configuration through a dedicated validation pipeline. This pipeline enforces type safety, applies default values, and handles errors automatically during the environment variable substitution process.

Yes, you can use environment variable substitution in YAML files for LiteLLM-RS. The configuration loading process automatically replaces variables like ${JWT_SECRET} with actual environment values before validating them against type-safe Rust models.

YAML configuration validation fails when the parsed data does not match the type-safe Rust models or required defaults. The validation pipeline catches these structural or type mismatches during loading and environment variable substitution, returning specific error handling messages.
