Module AirServiceProvider 

AirServiceProvider

High-level API surface for Air service methods.

RESPONSIBILITIES

• Service Facade: Provide convenient, high-level interface to Air daemon
• Authentication: Manage user authentication and credentials
• Updates: Check for and download application updates
• File Indexing: Query Air’s file search and indexing capabilities
• System Monitoring: Retrieve system metrics and health data
• Graceful Degradation: Handle Air unavailability with fallbacks

ARCHITECTURAL ROLE

AirServiceProvider acts as a facade over the raw AirClient, providing:

• Simplified API for common operations
• Automatic error handling and translation
• Request ID generation for tracing
• Connection state management

Application ──► AirServiceProvider ──► AirClient ──► gRPC ──► Air Daemon

Dependencies

• AirClient: Low-level gRPC client
• uuid: For generating request identifiers
• CommonLibrary::Error::CommonError: Error types

Dependents

• Binary::Service::VineStart: Initializes Air service
• MountainEnvironment: Can delegate to Air when available

IMPLEMENTATION

This implementation provides a fully functional provider that wraps the AirClient type with automatic request ID generation and error handling.

ERROR HANDLING

All operations return Result<T, CommonError> with:

• Translated gRPC errors to appropriate CommonError types
• Request IDs included in logs for tracing
• Graceful fallback to local operations when Air is unavailable

PERFORMANCE

• Request ID generation uses UUID v4 (cryptographically random)
• Thread-safe operations via Arc<AirClient>
• Non-blocking async operations via tokio

VSCODE REFERENCE

Patterns borrowed from VS Code:

• vs/platform/update/common/updateService.ts - Update management
• vs/platform/authentication/common/authenticationService.ts - Auth handling
• vs/platform/filesystem/common/filesystem.ts - File indexing

MODULE CONTENTS

• AirServiceProvider: Main provider struct
• generate_request_id: Helper function for UUID generation

Modules

GenerateRequestID

Generate a fresh UUID-v4 (simple form) for use as an Air request id. Each Air RPC carries one of these so Mountain can correlate replies with the originating call across log lines + traces.

Structs

AirServiceProvider

AirServiceProvider provides a high-level, convenient interface to the Air daemon service.
