YichiZhang0613 opened a new issue, #7174:
URL: https://github.com/apache/arrow-rs/issues/7174
In arrow-rs-master/arrow-data/src/ffi.rs, the code panics when index <
self.num_buffers(), while the comment indicates that code will panic when index
<= self.num_buffers().
```rust
/// # Panic
/// Panics if index exceeds the number of buffers or the buffer is not
correctly aligned
#[inline]
pub fn buffer(&self, index: usize) -> *const u8 {
assert!(!self.buffers.is_null());
assert!(index < self.num_buffers());
// SAFETY:
// If buffers is not null must be valid for reads up to num_buffers
unsafe { std::ptr::read_unaligned((self.buffers as *mut *const
u8).add(index)) }
}
```
