pub struct FragmentHeaderWriter<'a> {
    pub bytes: &'a mut [u8],
}

Fields

bytes: &'a mut [u8]

Implementations

impl<'a> FragmentHeaderWriter<'a>

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

Creates a new FragmentHeaderWriter from the given data slice.

pub fn header_len(&self) -> usize

Returns the length of the Fragment header.

pub fn set_next_header(&mut self, next_header: u8)

Sets the next header field.

Identifies the type of the next header.

pub fn set_reserved(&mut self, reserved: u8)

Sets the reserved field.

Should be all zeroes.

pub fn set_fragment_offset(&mut self, fragment_offset: u16)

Sets the fragment offset field.

Offset in 8 bytes relative to the start of the fragmentable part of the original packet.

pub fn set_res(&mut self, res: u8)

Sets the res field.

Reserved and should be all zeroes.

pub fn set_m_flag(&mut self, m_flag: bool)

Sets the M flag.

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

pub fn set_identification(&mut self, identification: u32)

Sets the identification field.

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