QUESTION
Problem: I want to write the same message to a textbox control that I am writing to a log file.
I have a windows form (Form1.cs) that calls a crosscutting class of static methods. In each of the crosscutting methods, they call WriteLogEntry to update a log file of what they are doing. I'd like to send back an event to Form1 so I can write the same log message to a control on the form.
I have looked at events but do not understand enough to make sense of the examples and have not found a simple enough example to do what I want. Can someone show me a simiple example of how to add an event to my code to accomplish this?

Answered 2017-Jun-14 at 02:26After not being able to figure out how to use a delegate to get back to the form, I tried another way. By creating an instance of Form1 on "MyClass", I was able to use a public method to write back to the form. Not the way I wanted, but it is a way to get it done for now. If anyone can explain how to do this a better way, please do so.

, and I would like to port it to Rust as an exercise.
One particularly ugly bit of the C++ code reads data from a UNIX file descriptor via read()
, and the resulting buffer is then cast to a struct via reinterpret_cast
. Unfortunately, I have no idea how to achieve a similar thing in Rust. The idea is to capture instances of le_advertising_info
from libbluetooth

Answered 2017-Feb-23 at 16:23In Rust you can use the unsafe
std::mem::transmute
function to cast from one type to another as long as they have the same size.
In the specific case where you are only casting from one pointer to another, though, this is not even required: you can just use as
