pub fn new(bytes: &'a [u8]) -> Result<Self, &'static str>

pub fn next_header(&self) -> u8

Returns the next header field.

Identifies the type of the next header.

pub fn reserved(&self) -> u8

Returns the reserved field.

Should be all zeroes.

pub fn fragment_offset(&self) -> u16

Returns the fragment offset field.

pub fn m_flag(&self) -> bool

Returns the M flag.

1 means more fragments follow, 0 means this is the last fragment.

pub fn identification(&self) -> u32

Returns the identification field.

Identifies the packet, generated by the sender, to help the receiver reassemble the fragments.
