In 2025, reading or writing byte by byte is a recipe for sluggish apps and angry users.
🌀 bufio lets you:
- Read stdin in large, efficient chunks
- Write to files without flooding syscalls
- Build TCP echo servers with live transformations
- Parse custom CSV fields using custom token splitters
✨ Bonus: Built-in Flush(), Peek(), and adjustable buffers make it surprisingly powerful — all inside the standard library.
