Struct RoutingHeaderWriter

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

Writes the Routing extension header fields.

Fields

bytes: &'a mut [u8]

Implementations

impl<'a> RoutingHeaderWriter<'a>

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

Creates a new RoutingHeaderWriter from the given data slice.

pub fn header_len(&self) -> usize

Returns the total header length in bytes.

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

Sets the next header field.

Specifies the type of the next header.

pub fn set_header_ext_len(&mut self, header_ext_len: u8)

Sets the header extension length field.

Length of the header in 8 bytes, not including the first 8 bytes.

E.g. Header length = (header_ext_len + 1) * 8.

pub fn set_routing_type(&mut self, routing_type: u8)

Sets the routing type field.

Value between 0 and 255, see IANA:

• 0: deprecated, since it enabled DoS attacks.
• 1: deprecated, used for the Nimrod project by DARPA.
• 2: allowed, limited version of type 0, used for Mobile IPv6.
• 3: allowed, RPL Source Route Header for low-power and lossy networks.
• 4: allowed, Segment Routing Header (SHR).

pub fn set_segments_left(&mut self, segments_left: u8)

Sets the segments left field.

Number of nodes this packet has to visit before reaching its final destination.

pub fn set_data(&mut self, data: &[u8]) -> Result<(), &'static str>

Sets the data field.

The data field is a variable-length field.

The first 4 bytes are reserved with zeroes.

If you set data then set blocks of 8 bytes.
