Struct PayloadHeaderFields 

pub struct PayloadHeaderFields { /* private fields */ }

A shared generic-payload-header field set every concrete payload layer embeds (RFC 7296 §3.2).

It carries the three caller-overridable generic-header fields — Next Payload, the Critical flag, and Payload Length — as Fields so a builder setter can pin any of them while compile() auto-fills the rest. A concrete payload layer holds one of these alongside its body fields and forwards PayloadHeaderFields::next_payload_override, PayloadHeaderFields::payload_length_override, and PayloadHeaderFields::critical into its IkePayload impl.

Implementations

impl PayloadHeaderFields

pub fn new() -> Self

A generic-header field set with builder defaults: Next Payload and Payload Length unset (auto-filled), Critical defaulted to clear.

pub fn set_next_payload(&mut self, next_payload: u8)

Pin the generic-header Next Payload explicitly (RFC 7296 §3.2).

pub fn set_length(&mut self, length: u16)

Pin the generic-header Payload Length explicitly (RFC 7296 §3.2).

pub fn set_critical(&mut self, critical: bool)

Set the Critical (C) flag explicitly (RFC 7296 §3.2).

pub fn next_payload_override(&self) -> Option<u8>

Caller-set Next Payload override, if any.

pub fn payload_length_override(&self) -> Option<u16>

Caller-set Payload Length override, if any.

pub fn critical(&self) -> bool

The Critical (C) flag value (defaulted to clear).
