Error Handling

This example demonstrates comprehensive error handling patterns.

What it shows

• Creating iterators that can produce errors
• Error propagation through transformations
• Error handling in both sync and async operations
• Graceful error handling patterns
• Partial results before errors occur

Run

cd examples/error-handling
go run main.go

Key concepts

• NewIteratorErr() creates iterators that can handle errors
• Errors stop processing immediately
• iter.Err() checks for errors after iteration
• Both sync and async operations propagate errors correctly
• You can get partial results before the error occurred
