Struct GoCompletionProvider 

pub struct GoCompletionProvider;

Go-specific completion provider (fallback)

This is a fallback provider for Go code when external LSP (gopls) is unavailable.

Behavior

Generates Go-specific completions including:

• Go keywords (package, import, func, const, var, type, struct, interface, etc.)
• Go-specific snippets (function templates, interface definitions, etc.)
• Go built-in functions (make, new, append, copy, delete, len, cap, etc.)
• Available symbols from code context

When Used

• External LSP (gopls) is not configured
• gopls is not installed or fails to start
• gopls times out or becomes unresponsive

Limitations

• No type inference or semantic analysis
• Cannot resolve imports or dependencies
• No project-aware completions
• Cannot determine variable scope or type information
• Limited to hardcoded keywords and patterns

Recommended Configuration

For production-quality Go completions, install and configure gopls:

go install github.com/golang/tools/gopls@latest

Then configure it in lsp-servers.yaml:

servers:
  go:
    - language: go
      executable: gopls
      args: ["serve"]
      enabled: true
