    it is possible that structure recovery might not be implemented yet. Did you check using debug info?

According to the official radare2 book, you have to reverse the struct manually by understanding the features of the program. Then you can overwrite the variable by struct names such as for instance:

If you have this code:

mov rax, qword [rsi + 8]

You can do:

"td struct ms1 { uint64_t a; int member1; };"
aht ms1.member1

Then the code will be documented:

[0x000052f0]> pd 1
0x000052f0      488b4608       mov rax, qword [rsi + ms1.member1]

There is nothing automatic in this process.
