Struct RouterAdvertisementHeader 

pub struct RouterAdvertisementHeader {
    pub cur_hop_limit: u8,
    pub managed_address_config: bool,
    pub other_config: bool,
    pub router_lifetime: u16,
}

ICMPv6 router advertisement header (part of “Neighbor Discovery Protocol” RFC 4861).

Fields

cur_hop_limit: u8

The default value that should be placed in the Hop Count field of the IP header for outgoing IP packets.

A value of zero means unspecified (by this router).

managed_address_config: bool

“Managed address configuration” flag.

When set, it indicates that addresses are available via Dynamic Host Configuration Protocol [DHCPv6].

If the M flag is set, the O flag is redundant and can be ignored because DHCPv6 will return all available configuration information.

other_config: bool

“Other configuration” flag.

When set, it indicates that other configuration information is available via DHCPv6. Examples of such information are DNS-related information or information on other servers within the network.

router_lifetime: u16

The lifetime associated with the default router in units of seconds.

The field can contain values up to 65535 and receivers should handle any value, while the sending rules in Section 6 of RFC 4861 limit the lifetime to 9000 seconds. A Lifetime of 0 indicates that the router is not a default router and SHOULD NOT appear on the default router list. The Router Lifetime applies only to the router’s usefulness as a default router; it does not apply to information contained in other message fields or options. Options that need time limits for their information include their own lifetime fields.

Implementations

impl RouterAdvertisementHeader

pub const MANAGED_ADDRESS_CONFIG_MASK: u8 = 0b1000_0000

Mask to read out the “Managed Address Configuration” flag out of the 5th byte of the ICMPv6 header.

pub const OTHER_CONFIG_MASK: u8 = 0b0100_0000

Mask to read out the “Other Configuration” flag out of the 5th byte of the ICMPv6 header.

pub fn from_bytes(bytes: [u8; 4]) -> Self

Decodes the header from the on the wire bytes.

pub fn to_bytes(&self) -> [u8; 4]

Converts the header to the on the wire bytes.

Trait Implementations

impl Clone for RouterAdvertisementHeader

fn clone(&self) -> RouterAdvertisementHeader

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for RouterAdvertisementHeader

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for RouterAdvertisementHeader

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for RouterAdvertisementHeader

fn cmp(&self, other: &RouterAdvertisementHeader) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for RouterAdvertisementHeader

fn eq(&self, other: &RouterAdvertisementHeader) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for RouterAdvertisementHeader

fn partial_cmp(&self, other: &RouterAdvertisementHeader) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
