Struct IPv6Writer

pub struct IPv6Writer<'a> {
    pub bytes: &'a mut [u8],
}

Writes IPv6 header fields.

Fields

bytes: &'a mut [u8]

Implementations

impl<'a> IPv6Writer<'a>

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

Creates a new IPv6Writer from the given data slice.

pub fn header_len(&self) -> usize

Returns the actual header length in bytes.

pub fn set_version(&mut self, version: u8)

Sets the version field.

Indicates the IP version number. Should be set to 6.

pub fn set_traffic_class(&mut self, traffic_class: u8)

Sets the traffic class field.

Specifies the priority of the packet.

pub fn set_flow_label(&mut self, flow_label: u32)

Sets the flow label field.

Identifies packets belonging to the same flow (group of packets).

pub fn set_payload_length(&mut self, payload_length: u16)

Sets the payload length field.

Specifies the length of the payload in bytes.

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

Sets the next header field.

Specifies the type of the next header, usually a transport protocol.

Shares the same values as the protocol field in an IPv4 header.

pub fn set_hop_limit(&mut self, hop_limit: u8)

Sets the hop limit field.

Replaces the time-to-live field in IPv4.

The value is decremented each time the packet is forwarded by a router.

When the value reaches 0, the packet is discarded, unless it has reached its destination.

pub fn set_src_addr(&mut self, src_addr: &[u8; 16])

Sets the source address field.

Unicast IPv6 address of the sender.

pub fn set_dest_addr(&mut self, dest_addr: &[u8; 16])

Sets the destination address field.

Unicast or multicast IPv6 address of the intended recipient.
