Module ResolveUIRequest 

ResolveUIRequest (Track)

RESPONSIBILITIES

This module provides a Tauri command handler for the UI to send back the result of a request-response interaction (like a dialog or message box).

Core Functions:

• Look up pending UI request by ID
• Remove request from pending requests map
• Send result through oneshot channel
• Handle dropped receiver errors gracefully

ARCHITECTURAL ROLE

ResolveUIRequest acts as the UI response handler in Track’s dispatch layer:

UI (Frontend) ──► ResolveUIRequest ──► Complete Pending Request ──► Return Result

KEY COMPONENTS

• Fn: Main UI request resolution function (public async fn Fn)

ERROR HANDLING

• Unknown or timed-out requests are logged as warnings
• Dropped receiver errors are logged and returned as errors
• Lock errors on pending requests map are propagated

LOGGING

• All UI request resolutions are logged at debug level
• Unknown/timed-out requests are logged at warn level
• Dropped receiver errors are logged at error level
• Log format: “[Track/UIRequest] Resolving UI request ID: {}”

PERFORMANCE CONSIDERATIONS

• Minimal locking duration on pending requests map
• Fast lookup and removal from HashMap
• Non-blocking channel sends

TODO

• Add request timeout handling
• Implement request cancellation support (VS Code compatibility)
• Add request metrics and telemetry
