-----------------------------------
Summary: [Rust] Debug implementation of Date32Array panics if
array contains negative values
Key: ARROW-11845
URL: https://issues.apache.org/jira/browse/ARROW-11845
Project: Apache Arrow
Issue Type: Bug
Components: Rust
Affects Versions: 3.0.0, 4.0.0
Reporter: Eric Burden
Fix For: 3.0.1
Attempting to print `Date32Array`s (and probably all Date/Time/Timestamp array
types) using Rust's debug print format macro (`println!("\{:?}",
date_32_array")`) causes a panic, as shown in the minimum reproducible example
below:
*Invocation:*
{code:java}
fn date32_print_panic() {
let mut date_32_builder = Date32Builder::new(1);
date_32_builder.append_value(-50).unwrap();
let date_32_array = date_32_builder.finish();
println!("{:?}", date_32_array);
}
{code}
*Result:*
{noformat}
PrimitiveArray<Date32>
[
thread 'demo::tests::date32_print_panic' panicked at 'called `Option::unwrap()`
on a `None` value', /home/.../rust/arrow/src/array/array_primitive.rs:226:54
note: run with `RUST_BACKTRACE=1` environment variable to display a
backtrace{noformat}
