#Rust
国内知名Rust社区贡献者Folyd，之前曾经给Rust贡献了一个优化的二分查找实现：《优化 Rust 标准库的 binary_search》。
但是这个实现，会导致在有多个重复元素的情况下，返回是不确定的，最终导致了币圈某产品的翻车，这里可以看到作者的后续推文。
我们回到这个问题本身：除了撤销这个修改，下一步应该在Rust标准库里增加多个重复元素的测试用例了吧？

Bitcoin is built on a distributed digital record called a blockchain. As the name implies, blockchain is a linked body of data, made up of units called blocks that contain information about each and every transaction, including date and time, total value, buyer and seller, and a unique identifying code for each exchange. Entries are strung together in chronological order, creating a digital chain of blocks. “Once a block is added to the blockchain, it becomes accessible to anyone who wishes to view it, acting as a public ledger of cryptocurrency transactions,” says Stacey Harris, consultant for Pelicoin, a network of cryptocurrency ATMs. Blockchain is decentralized, which means it’s not controlled by any one organization. “It’s like a Google Doc that anyone can work on,” says Buchi Okoro, CEO and co-founder of African cryptocurrency exchange Quidax. “Nobody owns it, but anyone who has a link can contribute to it. And as different people update it, your copy also gets updated.”
