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.
This is better in that there is far less boilerplate, but it doesn't solve everything. Async iteration was retrofitted onto an API that wasn't designed for it, and it shows. Features like BYOB (bring your own buffer) reads aren't accessible through iteration. The underlying complexity of readers, locks, and controllers are still there, just hidden. When something does go wrong, or when additional features of the API are needed, developers find themselves back in the weeds of the original API, trying to understand why their stream is "locked" or why releaseLock() didn't do what they expected or hunting down bottlenecks in code they don't control.
，这一点在safew官方版本下载中也有详细论述
The semantics around releasing locks with pending reads were also unclear for years. If you called read() but didn't await it, then called releaseLock(), what happened? The spec was recently clarified to cancel pending reads on lock release – but implementations varied, and code that relied on the previous unspecified behavior can break.
First: mockToString — The Lie That Defeats The Check
■ 视点12月21日，陕西省西安市灞桥区豁口村发生一起恶犬撕咬4岁男童事件。12月24日，西安市公安局灞桥分局发布通报称，伤人犬只系郭某饲养，未加管束窜出至村内道路，咬伤男童。案发后，郭某为逃避责任，将伤人犬只立即转移外地杀死掩埋藏匿。目前，郭某和协助其掩盖事实的张某二人已被刑事拘留。尽管警方通报中，受伤男孩“情况基本平稳”，但更多报道透露的细节显示，男孩受到的伤害可谓触目惊心。其门诊病历显示：“右侧上下肢多发皮肤裂伤。昏迷状，呼之不应，呼吸急促。”养狗导致4岁儿童受到严重伤害，饲养者无疑要承担严肃的法律责任。警方通报已经证明，这起事件的直接原因，正是饲养者对伤人犬只缺乏管束。根据民法典规定，遗弃、逃逸的动物造成他人伤害，由动物原饲养人或管理人承担侵权责任。值得注意的是，西安这起事件案发后，饲养者郭某为逃避责任，将伤人犬只立即转移外地杀死掩埋藏匿，其残忍做法同样令爱宠人士所不容。可见，这种企图逃避法律责任的做法，只会让自己付出更大的代价。西安这起恶犬伤人事件发生在农村，虽然相比城市对养犬的严格管理，农村执行养犬规定往往要宽松一些，但该有的规范还是应当得到强调和遵循。比如，很多农村地区仍然存在犬只放养的情况。这种极端不负责任的行为，不仅给他人带来安全隐患，也可能导致流浪犬增加、狂犬病流行等治理难题。随着城乡融合的推进，一些习以为常的错误做法必须改改了。“法网恢恢，疏而不漏”。如今，警方已查获犬只尸体，随着相关证据浮出水面，饲养者势必为自己的鲁莽和无知承担严肃责任，“杀犬藏尸”只是一场闹剧。对广大宠物主而言，不约束好自己的行为，也不利于构建宠物友好的社会氛围和舆论环境。养犬者应从自己做起，推动文明养犬风尚持续形成，社会才能有更高的包容度，为宠物活动提供更多便利与支持。□南木（媒体人）SourcePh" style="display:none"
