Struct Ipv6Builder 

pub struct Ipv6Builder { /* private fields */ }

Builder for IPv6 packet headers.

Implementations

impl Ipv6Builder

pub fn new() -> Self

Create a new IPv6 builder with default values.

pub fn src(self, src: Ipv6Addr) -> Self

Set the source IPv6 address.

pub fn dst(self, dst: Ipv6Addr) -> Self

Set the destination IPv6 address.

pub fn hop_limit(self, hlim: u8) -> Self

Set the Hop Limit (equivalent to TTL in IPv4).

pub fn traffic_class(self, tc: u8) -> Self

Set the Traffic Class field.

pub fn flow_label(self, fl: u32) -> Self

Set the Flow Label (20 bits; upper 12 bits are ignored).

pub fn next_header(self, nh: u8) -> Self

Set the Next Header field.

pub fn payload<T: Into<Vec<u8>>>(self, data: T) -> Self

Set the payload bytes (appended after the 40-byte header).

pub fn auto_length(self, auto: bool) -> Self

Configure automatic payload length calculation (default: true).

pub fn payload_len(self, len: u16) -> Self

Manually override the payload length field.

Only used when auto_length is false.

pub fn header_size(&self) -> usize

Get the header size (always 40 bytes for IPv6).

pub fn packet_size(&self) -> usize

Get the total packet size (header + payload).

pub fn build(&self) -> Vec<u8>

Build the IPv6 header + payload into a byte vector.

Byte layout:

• Byte 0: version (6) in high 4 bits | TC high nibble in low 4 bits
• Byte 1: TC low nibble in high 4 bits | FL bits 19-16 in low 4 bits
• Bytes 2-3: FL bits 15-0 (big-endian)
• Bytes 4-5: payload_len (big-endian)
• Byte 6: next_header
• Byte 7: hop_limit
• Bytes 8-23: source address (16 bytes)
• Bytes 24-39: destination address (16 bytes)
• Bytes 40+: payload
