quick-x | game engine base on cocos2d-x | Game Engine library

I'm trying to use the quick_xml::se::to_string function. This seems to be a public function, since it is in the publicly available docs, is marked as pub in the quick_xml sources, and seems to work fine in the quick_xml unit tests. Here's my code:

I'm attempting to write an incremental XML parser in Rust using quick_xml.

Some of the XML files will not fit in memory (on my laptop) so I'm trying to only store relevant chunks of each file in a buffer of Vec.

Within each file chunk of Vec I want to store borrows to slices in some struct Data

quick_xml provides a read_event method which appends to the buffer and returns a quick_xml::events::Event (an enum containing a struct with a buf: Cow<'a, [u8]> field which borrows from the buffer)

Essentially I want to take the data referenced by the Event and store it in my Data struct.

However the borrow checker has a heart attack because the Event only lives for the call to read_event and I'm trying to keep a reference to it that lives as long as the data in the buffer.

The code below is the implementation of what I have tried to describe above. Could I get some help in storing a borrow to the underlying buf from an Event?

I'm writing a Rust command line program to grep log files. It reads the input files line by line, and creates records containing the "base" log line (with timestamp, logging level, thread name, class name etc) and "extra" log lines (containing embedded XML or JSON messages). Here's a simplified example:

I'm very new to Rust, and am still trying to get the hang of working with it. It's cool, but I'm clearly missing something with an exercise I gave myself. For reference, I'm using rustc 1.39.0.

I wanted to try to write a simple program to read the XML from MSBuild's code analysis, which outputs some fairly simple XML. The problem I think is that there is an element (PATH) which is usually empty, but sometimes can contain elements under it. The bigger problem is that I suck at Rust (and I don't usually deal with XML), and I'm not really sure how to correctly set up the structs I need for deserialization. I'm using Serde and quick_xml. When I had PATH set as a String and worked with XML that did not have an SFA element under PATH, my tests worked. But once I figured out how that tag was supposed to be used and updated my structs accordingly, I constantly get the error:

I'm trying to encapsulate an XML parser using quick-xml that takes some specific XML in entry. The main code is the following:

I've just added an external crate to my Rust project:
