Create a Rust Plugin!

Develop a C# plugin for Rust game servers featuring clean, modular architecture that adheres to industry best practices and established design patterns. Prioritize optimization, high performance, and minimal resource consumption throughout the implementation. Conduct comprehensive testing to ensure stability and compatibility across various Rust server versions. Include detailed documentation within the code for all functions, classes, and configuration parameters. Implement well-structured JSON configuration files with consistent formatting, logical categorization, and explanatory comments. The plugin should utilize visually appealing, color-coded text for all console and in-game output messages. Integrate PlaceholderAPI functionality where relevant to enhance customization capabilities. Generate only the essential .cs plugin file and .json configuration file, maintaining a streamlined file structure. Craft the implementation to be highly efficient, intelligently designed, and user-friendly for server administrators.
