Rust Recoil Script with ImGui Menu

Act as a highly experienced Rust developer specializing in high-performance systems and the creation of interactive, low-latency user interfaces, specifically for gaming applications.

Your task is to design and implement the complete conceptual structure and core logic for an advanced weapon recoil control script. This script must integrate a customizable user interface built with the ImGui library to allow in-game configuration.

Implementation Requirements:

1. Recoil Dynamics Core: Implement the underlying Rust logic necessary to calculate and apply weapon recoil dynamics in a manner that is highly optimized for minimal latency.
2. ImGui Customization Menu: Integrate a fully functional, customizable ImGui menu that allows the user to modify critical weapon parameters. This menu must enable customization for:
   • Weapon Selection (based on a provided list).
   • Scope Selection (based on a provided list).
   • Attachment Configuration (based on a provided list).
   • Recoil Parameter Tuning.
3. User Interaction: The menu must be controlled by keyboard input, specifically using the 'Insert' key to toggle the menu visibility.
4. Execution Context: The script must be designed to operate as an external executable (.exe) that hooks into the game environment, ensuring the recoil control logic only activates when the target game is actively running.
5. Code Quality: The final implementation must adhere strictly to Rust best practices, including clear modularization, robust error handling, and comprehensive documentation (doc comments) explaining every major function and structure.

Constraints and Performance Rules:

• Performance: The core recoil calculation and UI rendering must prioritize high performance and extremely low latency, ensuring no perceptible delay during gameplay.
• Style: Follow idiomatic Rust coding standards and ImGui integration patterns.

Input Variables (To be integrated into the structure):

The implementation must conceptually use the following variables as dynamic inputs:

• ${weaponType}: The specific type of weapon for which the recoil script is applied.
• ${menuTheme:default}: The chosen visual theme for the ImGui menu (defaulting to a standard theme).
• ${interactionMode:mouse}: The primary input method for menu interaction.
• ${gunList}: A dynamic list of all available guns in the game.
• ${scopeList}: A dynamic list of all available scopes in the game.
• ${attachmentList}: A dynamic list of all available attachments in the game.

Desired Output:

Provide the complete, well-structured, and highly detailed Rust code implementation, along with a high-level explanation of the architecture, focusing on how the UI interacts with the core physics simulation.
