nlprule，Rust 实现的 NLP 库
nlprule 使用 LanguageTool 中的资源为NLP实现了基于规则和查找的方法。
Github链接，https://github.com/bminixhofer/nlprule
from nlprule import Tokenizer, Rules
tokenizer = Tokenizer.load("en")
rules = Rules.load("en", tokenizer)
rules.correct("He wants that you send him an email.")
# returns: 'He wants you to send him an email.'
rules.correct("I can due his homework.")
# returns: 'I can do his homework.'
for s in rules.suggest("She was not been here since Monday."):
print(s.start, s.end, s.replacements, s.source, s.message)
# prints:
# 4 16 ['was not', 'has not been'] WAS_BEEN.1 Did you mean was not or has not been?
for sentence in tokenizer.pipe("A brief example is shown."):
for token in sentence:
print(
repr(token.text).ljust(10),
repr(token.span).ljust(10),
repr(token.tags).ljust(24),
repr(token.lemmas).ljust(24),
repr(token.chunks).ljust(24),
)
# prints:
# '' (0, 0) ['SENT_START'] [] []
# 'A' (0, 1) ['DT'] ['A', 'a'] ['B-NP-singular']
# 'brief' (2, 7) ['JJ'] ['brief'] ['I-NP-singular']
# 'example' (8, 15) ['NN:UN'] ['example'] ['E-NP-singular']
# 'is' (16, 18) ['VBZ'] ['be', 'is'] ['B-VP']
# 'shown' (19, 24) ['VBN'] ['show', 'shown'] ['I-VP']
# '.' (24, 25) ['.', 'PCT', 'SENT_END'] ['.'] ['O']
# and every call here takes less than 1ms! (on an i5 8600k)
Fly.io 升级Tokio到1.x
Fly.io 基于Rust 的 Tokio 和 Hyper 实现负载均衡，Tokio 升级到 v1.x，Fly.io 将其使用的 Tokio 从 v0.2 升级到 v1.x，并认为虽然是一个主要版本的升级，但升级过程并不难。
这篇博客文章记录了一些笔记，文章链接，https://fly.io/blog/the-tokio-1-x-upgrade/
PyO3 为 Rust 1.41 提供支持
在 Debian Buster，Alpine 3.12 和其他使用较旧 Rust 编译器版本 v1.41 的平台，PyO3 不能与Rust v1.41一起编译，目前已提供支持 Rust v1.41。
