Rust canister canister interface

I use rust to write a canist and deploy it to the IC main network. Why the Canister Interface cannot be viewed in the rocks browser? My cansiter: Principal qy2to-tqaaa-aaaai-qiyjq-cai | ic.rocks.
Maybe the did file not upload successfully? How to upload a did file?

OGY canister ,Canister Interface can be viewed.

For rust canisters you can add a __get_candid_interface_tmp_hack() method to your actor that serves the .did file, like this:
https://github.com/dfinity/ic/blob/c48280bbeec347a6b73160199566c612bd8ccbf7/rs/nns/governance/canister/canister.rs#L944
Motoko canisters automatically provide this method for you.

Then you’ll be able to see it on ic.rocks (and here: https://k7gat-daaaa-aaaae-qaahq-cai.ic0.app/canister/qy2to-tqaaa-aaaai-qiyjq-cai )
