Function mz_repr::row::read_byte_array_extending_negative

unsafe fn read_byte_array_extending_negative<const N: usize>(
    data: &[u8],
    offset: &mut usize,
    length: usize,
) -> [u8; N]

Read length bytes from data at offset, updating the latter. Extend the resulting buffer to a negative N-byte twos complement integer by filling the remaining bits with 1.

SAFETY:

• length <= N
• offset + length <= data.len()
