Usage

The Go Struct Analyzer provides several ways to inspect and optimize struct layouts:

Feature	What it shows	How to access
Hover Information	Field size, alignment, offset, padding	Hover over struct field or name
Inline Annotations	Struct and field sizes in the editor	Code lens above structs (toggle in settings)
Warnings & Diagnostics	Optimization opportunities, GC pressure	Yellow/blue underlines + Problems panel
Quick Fix	One-click field reorder	Lightbulb or Ctrl+. on warning
Analyze Panel	Side-by-side layout comparison	Code lens click or Command Palette
Configuration	All settings reference	VS Code settings UI

Each feature is designed to work without configuration — install the extension and open a Go file.

Zed	Install the Zed dev extension from editors/zed/
Emacs	Emacs setup guide — eglot (Emacs 29+) or lsp-mode
