You might assume this pattern is inherent to streaming. It isn't. The reader acquisition, the lock management, and the { value, done } protocol are all just design choices, not requirements. They are artifacts of how and when the Web streams spec was written. Async iteration exists precisely to handle sequences that arrive over time, but async iteration did not yet exist when the streams specification was written. The complexity here is pure API overhead, not fundamental necessity.

However, stylecloud was hacky and fragile, and a number of features I wanted to add such as non-90-degree word rotation, transparent backgrounds, and SVG output flat-out were not possible to add due to its dependency on Python’s wordcloud/matplotlib, and also the package was really slow. The only way to add the features I wanted was to build something from scratch: Rust fit the bill.
