aiterio 0.1.4

AsyncIterator based connectable components

aiterio

tl;dr

aiterio is a minimal library to build asynchronous pipelines based on Python's asynchronous iterators.

It transforms a syntax like:

aiterator_3(aiterator_2(aiterator_1(source_data)))

or

aiterator_1 = fn_1(source_data)
aiterator_2 = fn_2(aiterator_1)
aiterator_3 = fn_3(aiterator_3)

async for item in aiterator_3:
    pass

into

await Component1().source(source_data).then(Component2()).then(Component3()).run()
# or
for item in Component1().source(source_data).then(Component2()).then(Component3()):
    pass

Why use this?

• Minimal library without dependencies
• Simplifies usage of asynchronous iterators
• Makes it easy to create components with a single responsibility and to test them
• Built-in shutdown logic
