Gemini for Code: Go and Rust
Idiomatic Go, error returns, table-driven tests; Rust ownership.
What You Will Learn
- Use Gemini idiomatically in Go.
- Generate table-driven tests.
- Handle errors idiomatically.
- Use Rust ownership patterns.
- Apply language idioms.
Why This Matters
Go and Rust have strong idioms. Gemini recognizes these and produces idiomatic code when you signal them.
Concept Explained
Go's idioms (error returns, table tests, context.Context) are well-recognized. Rust's ownership, traits, and Result types are also well-supported.
How It Works
Start patterns idiomatically. Gemini continues them. Use error returns in Go. Use Result
Step-by-Step Tutorial
1. Idiomatic Go errors
Write result, err := someFunc() then if err != nil {. Gemini completes.2. Table-driven tests
Start with tests := []struct{...}. Gemini suggests test cases.3. Context.Context
Use func foo(ctx context.Context, ...). Gemini suggests context-aware patterns.4. Rust ownership
Use fn foo(x: &str) for borrows, fn foo(x: String) for ownership.5. Rust Result
Use ResultReal-World Example
A Go developer started a table-driven test. Gemini suggested 5 test cases covering typical values, edge cases (0, -1, max int). Shipped 5 passing tests in 90 seconds.
Example Prompts / Commands / Code
func TestFormat(t *testing.T) { tests := []struct { name string; input int; want string }{ // Gemini suggests test cases } }func LoadConfig(path string) (*Config, error) { data, err := os.ReadFile(path) // Gemini suggests: if err != nil { return nil, fmt.Errorf(read config: %w, err) } }Common Mistakes
- Using try/catch-style errors in Go.
- Skipping context.Context.
- Writing verbose tests instead of table-driven.
- Forgetting Rust ownership patterns.
Best Practices
- Start patterns idiomatically.
- Always use error returns in Go.
- Use context.Context in signatures.
- Start table tests with struct definition.
- Use Result
Troubleshooting
| Problem | How to Fix |
|---|---|
| Gemini suggests non-idiomatic code | Specify: use idiomatic Go. |
| Rust ownership confused | Specify: use &str for borrows. |
Practical Exercise
Your Turn
Write a Go function with error returns. Ask Gemini for table-driven tests. Try Rust with Result
Key Takeaways
- Go idioms (errors, table tests, context) are well-recognized.
- Start the pattern; Gemini continues.
- Use error returns, not try/catch.
- Use Result
- Specify idiomatic.
