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