Rust nom to achieve how to use the mysql binlog parsing tool, many novices are not very clear about this, in order to help you solve this problem, the following editor will explain in detail for you, people with this need can come to learn, I hope you can gain something.

To tell you the truth, parsing binaries with nom is easier than parsing text, because routines and tools are very clear, the reason for the slow progress of the project is that MySQL binlog's documentation is a bit cramped, and some instructions are inconsistent with mysqlbinglog tools. I can only try to find other implemented MySQL binlog project references, specific to a field when these projects are not very complete. As a last resort, I had to look at the source code of mysql-server and try to parse all the fields with my hello world-level C++. But some fields are too complex or not very important, so I put them aside for the time being.

I have to complain here that in order to implement this project, I have seen similar implementations of five languages: cresume, Go, Java, and Python. C++ has a lot of symbols, but it can still understand the meaning; c, because the expressive force is not enough, the code is a little tedious; Java is really verbose, only one line is written in a method, and that line is another function ~; Go doesn't even want to see it; Python has good performance, but it may be the author's problem, and the code is a bit messy. Of course, my code is not much better: (in order to quickly use a big enum to represent all events, it may have to be refactored soon, but this is a human problem. In terms of performance, Rust is the only file in a static language. Because of the limited time, the test case is not perfect, if you encounter problems during the test, you can mention Issue, it is best to attach the binlog file at that time to help me enrich the test case.
