URL: https://github.com/apache/arrow-rs/issues/4829
**Describe the bug**
Casting from string to decimal does not perform a precision overflow check.
**To Reproduce**
```rust
use arrow::array::types::Decimal128Type;
use arrow::array::{AsArray, StringArray};
use arrow::compute::{cast_with_options, CastOptions};
use arrow::datatypes::DataType;
fn main() {
let str_array = StringArray::from(vec!["1000".to_string()]);
let output_type = DataType::Decimal128(10, 8);
let mut option = CastOptions::default();
option.safe = false;
let casted_array = cast_with_options(&str_array, &output_type,
&option).unwrap();
let decimal_array = casted_array.as_primitive::<Decimal128Type>();
println!("{:?}", decimal_array.value_as_string(0));
}
```
The execution result of the above program is "10.00000000".
**Expected behavior**
<!--
A clear and concise description of what you expected to happen.
-->
It should panic and report an overflow.
**Additional context**
<!--
Add any other context about the problem here.
