binread | Rust crate for helping parse structs | Parser library

When calling a specific endpoint in C# which works without issues in Postman (or via Firefox), I'm getting an empty response.

The url I'm calling is returning a collection of data. In the url parameters I can specify how much of said data I want. I've inspected the response size in Postman, and when I limit the amount of data requested in my C# call such that the response is around 700kb, then I get a JSON response back.

However, if I exceed this size in the C# call, then the response is empty '{ }' and the ContentLength returned = -1 (the statusCode returned is 200, so this seems fine at least). This same request which fails in C# works fine within Postman and Firefox however...

I somehow suspect this occurs because either the deserializer's buffer is not big enough OR because the response is still in transit and the code somehow continues executing before it has read the whole response body...

See below for the 3 implementations which I've tested:

I understand how this can be down when uploading directly to Cloudinary using the below syntax and passing the folder name as an argument.

I have an app whose sole purpose is to seed data files and add the data to different CSVs which are zipped and exported by the user. My application controller is filled with lines that all look like this:

i am trying to read data from binary file, i can read all data types except when its an array of strings, i am getting the error " Object must be an array of primitives"

here is where i get the error in my code

I am trying to read an ADS datastream from a TwinCAT3 Project.

The function I wrote should read the datastream whenever the CycleCount (coming from the SPS) changes its value - so CycleCount is the trigger for the callback function and is checked for a change every millisecond.

The datastream to be read consists of a structure containing the two values "nCycleCount" (DWORD-4Bytes) and "TStamp" (ULINT-8Bytes). Therefore the whole stream is containing 12 bytes of data.

One cycle in TwinCAT is configured as 0.5ms, so the variable CycleCount should change 2 times per second (if the PLC-tasks cycle time is one cycle-tick). As my program is checking every millisecond if the variable CycleCount changed, the callback function should be called every millisecond and write the timestamp to a Buffer ("myBuffer"). But I noticed that for a runtime of 2 seconds I only receive 1000 values (instead of 2000 expected) and I can't find the reason why?

The PLC task in TwinCAT3 seems to show the correct values, but when reading them with MatLab the timestamp values are incorrect and not every millisecond as stated before:

These are some outputs from Matlab where the CycleCounter is written to column 1 and timestamp is written to column 2:

I use the following Codes in TwinCAT to define the structure and Main-Program:
