[GitHub] [arrow-adbc] paleolimbot opened a new pull request, #703: feat(r): Improve error communication

paleolimbot opened a new pull request, #703:
URL: https://github.com/apache/arrow-adbc/pull/703

   Before this PR, errors coming from ADBC were rather unhelpfully labelled:
   
   ``` r
   library(adbcdrivermanager)
   
   db <- adbc_database_init(adbc_driver_void())
   adbc_database_release(db)
   adbc_database_release(db)
   #> Error in stop_for_error(status, error): ADBC_STATUS_INVALID_STATE (6)
   ```
   
   After this PR, the source of the error is better communicated and errors are given a custom class so they can be caught appropriately:
   
   ``` r
   library(adbcdrivermanager)
   
   db <- adbc_database_init(adbc_driver_void())
   adbc_database_release(db)
   adbc_database_release(db)
   #> Error in adbc_database_release(db): ADBC_STATUS_INVALID_STATE (6)
   
   tryCatch({
     db <- adbc_database_init(adbc_driver_void())
     adbc_database_release(db)
     adbc_database_release(db)
   }, adbc_status_invalid_state = function(e) {
     message(sprintf("Just warning for ADBC status with code %d", e$error$status))
   })
   #> Just warning for ADBC status with code 6
   ```
