Struct RouterAdvertisementPayloadSlice 

pub struct RouterAdvertisementPayloadSlice<'a> { /* private fields */ }

Borrowed payload of a Router Advertisement message (RFC 4861, Section 4.2).

The full packet layout is:

 0                   1                   2                   3

In this crate, Cur Hop Limit, M, O, and Router Lifetime are represented by crate::icmpv6::RouterAdvertisementHeader in crate::Icmpv6Type::RouterAdvertisement. This slice starts after that fixed part and contains:

• Reachable Time
• Retrans Timer
• options

Implementations

impl<'a> RouterAdvertisementPayloadSlice<'a>

pub const FIXED_PART_LEN: usize = RouterAdvertisementPayload::LEN

Length of the fixed payload part (Reachable Time and Retrans Timer) in bytes.

pub fn from_slice(slice: &'a [u8]) -> Result<Self, LenError>

pub fn slice(&self) -> &'a [u8]

Returns the full payload slice.

pub fn reachable_time(&self) -> u32

Reachable time in milliseconds.

pub fn retrans_timer(&self) -> u32

pub fn options(&self) -> &'a [u8]

Returns the Neighbor Discovery options.

pub fn options_iterator(&self) -> NdpOptionsIterator<'a>

Returns an iterator over Neighbor Discovery options.

pub fn to_payload(&self) -> (RouterAdvertisementPayload, &'a [u8])

Convert to an owned structured payload and return trailing options.
