Rust CDK - How to catch panic/trap when calling another canister which traps?

rckprtr · October 14, 2021, 12:49am

I asked a similar question before and it does not appear its possible to catch this error:

Here is my code:

dscvr-one/ic-drip/blob/better-props/src/ic_loot_rs/lib.rs#L540

    
      
          
          
#[update]
          fn transfer_to(user: Principal, token_id: u64) -> bool {
              return storage::get_mut::<AddressBook>().transfer_to(user, token_id);
          }
          
          
#[update]
          async fn transfer_with_notify(user_id: Principal, token_id: u64) -> bool {
              let address_book = storage::get_mut::<AddressBook>();
              if address_book.transfer_to(user_id, token_id) {
                  match ic_cdk::call(
                      user_id,
                      "transfer_notification",
                      (TransferNotification {
                          to: user_id,
                          from: ic_cdk::caller(),
                          token_id: token_id,
                          amount: 1,
                      },),
                  )
                  .await as CallResult<()>
