Can eip-rs Read and Write UDTs?

I need a grab a UDT instance from my CompactLogix PLCs, can that be done? And then Mapped to a struct?

Example UDT on PLC

- Type: MyUDT
  - MyDint1 : DINT
  - MyDint2: DINT
  - MyString1 : STRING
  - MyString2 : STRING

Path to an instance on PLC that is in Program1 \Program1.MyUdtInstance1

Rust Type: 

struct MyUDT {
    MyDint1: i32,
    MyDint2: i32,
    MyString1 : String
    MyString2 : String
}

the lib can read UDT, please check examples in the repo.

I don't see examples of fetching a UDT instance, I only see an example of reading individual tags that ate in side a UDT, but not the whole UDT.

Could you direct me to the example you are talking about?

Check out ab-tag-read-fragmented.rs. It reads a UDT full of strings.
