phillipleblanc opened a new issue, #22:
URL: https://github.com/apache/arrow-rs-object-store/issues/22
**Describe the bug**
Attempting to convert a string which contains a valid large date in the ISO
format (i.e. `+10999-12-31`) will result in the following error:
`CastError("Cannot cast string '+10999-12-31' to value of Date32 type")`
According to ISO 8601:
> Four digits or more for the year. Years in the range 0000 to 9999 will be
pre-padded by zero to ensure four digits. Years outside that range will have a
prefixed positive or negative symbol.
**To Reproduce**
```rust
#[test]
fn test_cast_string_with_large_date_to_date32() {
let array = Arc::new(StringArray::from(vec![
Some("+10999-12-31"),
Some("-0010-02-28")
])) as ArrayRef;
let to_type = DataType::Date32;
let options = CastOptions {
safe: false,
format_options: FormatOptions::default(),
};
let b = cast_with_options(&array, &to_type, &options).unwrap();
let c = b.as_primitive::<Date32Type>();
assert_eq!(3298139, c.value(0));
assert_eq!(-723122, c.value(1));
}
```
**Expected behavior**
The cast works as expected.
