Rust Platform

🎯 In Python, you can chain operations in a list comprehension or with itertools:

# Filter and transform in one comprehension
result = [x * 2 for x in data if x > 0]

# Multiple steps with itertools
from itertools import chain
flat = list(chain.from_iterable(nested_lists))
longest = sorted(words, key=len)[-1]

Rust takes the chaining idea further — every iterator adapter returns a new iterator, so you can build multi-step pipelines that read top-to-bottom, like Unix pipes. And because each step is lazy, Rust fuses them into efficient single-pass execution.

Building pipelines

Each method returns a new iterator that wraps the previous one. Nothing executes until a consuming adapter (.collect(), .sum() …
