             Summary: [Rust] Divide by zero in arrays/builder.rs
                 Key: ARROW-8808
                 URL: https://issues.apache.org/jira/browse/ARROW-8808
             Project: Apache Arrow
          Issue Type: Bug
          Components: Rust
            Reporter: Andy Grove
             Fix For: 1.0.0


Integration testing exposed a bug in cases where values_data.len() is zero. This fails with divide by zero error.
{code:java}
// check that values_data length is multiple of len
assert!(
    values_data.len() / len == self.list_len as usize,
    "Values of FixedSizeList must have equal lengths, values have length {} and list has {}",
    values_data.len(),
    len
); {code}
