This lets a caller take appropriate action (or give an error, or give a
better warning) if a lossy conversion occurs.
``` r
library(nanoarrow)
array <- as_nanoarrow_array(2^54, schema = na_int64())
convert_array(array, double())
#> Warning in convert_array.default(array, double()): 1 value(s) may have
incurred
#> loss of precision in conversion to double()
#> [1] 1.80144e+16
withCallingHandlers(
convert_array(array, double()),
nanoarrow_warning_lossy_conversion = function(x) {
warning(
"This is a better explanation of what happened!",
call. = conditionCall(x)
)
tryInvokeRestart("muffleWarning")
}
)
#> Warning in (function (x) : This is a better explanation of what happened!
#> [1] 1.80144e+16
```
