This section begins with the first program and the introduction Use of Cargo. hello world Create Hello manually_ World folder: mkdir hello_world cd hello_world Then create a hello_world.rs file, i.e. t rust source file: touch hello_world.rs Write the follow ...

Five data types and application scenarios of Redis Redis has five data types, namely, string,list,hash,set,zset(sort set). I think this point should be clear to all partners who have a little knowledge of redis. Next, let's discuss the application scenarios of these five data types. [get notes] string This type is believed to be the most fam ...

Here are some points in the compilation process of TiDB. Although in theory, the source code downloaded from github can be compiled after decompression, in the actual operation process, there may still be errors due to various reasons. This paper shares several problems and solutions in the actual operation process. The environment used in t ...

Author: Wang DongyangprefaceSorting and binary search are very common algorithms in computer science leveldb memdb source code analysis (Part 2): Rust implementation You can see that many methods use binary search. This paper will compare some characteristics and differences in sorting and search methods between Go and Rust. For Go, we mainly u ...

Recently, there has been a rush of trust in the front-end circle. All front-end tools that can be rewritten with trust are rewritten with trust. The tool introduced today is bable: swc, a tool that converts ES6 into ES5.Moreover, on the official website of swc, it is very straightforward to say that they are benchmarking with babel. swc and bab ...

1281. Difference between bit product sum of integers: There are n rings in total, and the color of the ring can be one of red, green and blue. These rings are distributed on 10 rods numbered 0 to 9. Give you a string rings with a length of 2n to represent the distribution of these n rings on the rod. Every two characters in rings form a ...

prefaceThe memdb module in leveldb uses skiplist as a kv memory storage, and the related code implementation is very beautiful. The following is described above:Compare the implementation of query, insert and delete in c + + and golangAnalyze the places in the golang version that can be optimized, and then optimize the t rust versionThen in thi ...

10.1. CountDownLatch (counter) In the official documents, the explanation of this block is complex. In short, this class is a subtraction counter, which is generally used to calculate the execution times of threads and execute an operation when it reaches 0. For example, suppose there are six students in a class. Now after school, if the ...
