Function hexdump_very_ex_rs 

pub fn hexdump_very_ex_rs<W: Write>(
    writer: &mut W,
    data: &[u8],
    disp_addr: u64,
) -> Result

Do a hex dump against a writer, formatting data as 32-bit words (host endianness) alongside an 8-bit ASCII panel on the side, displaying up to 16 bytes per line.

The “very” in the name follows the Zircon kernel naming scheme.
