Struct netstack3_ip::device::OpaqueIid

pub struct OpaqueIid(/* private fields */);

An opaque interface identifier (IID).

Implementations

impl OpaqueIid

pub fn new<IF, ID>( prefix: Subnet<Ipv6Addr>, net_iface: IF, net_id: ID, dad_counter: OpaqueIidNonce, secret_key: &IidSecret, ) -> Self

where IF: AsRef<[u8]>, ID: AsRef<[u8]>,

Computes an opaque interface identifier (IID) using the algorithm in RFC 7217 Section 5.

Each argument to generate_opaque_interface_identifier corresponds to an argument from Section 5 of the RFC:

• prefix corresponds to the “Prefix” argument
• net_iface corresponds to the “Net_Iface” argument
• net_id corresponds to the “Network_ID” argument
• nonce corresponds to the “DAD_Counter” argument if nonce = [OpaqueIidNonce::DadCounter]
• secret_key corresponds to the “secret_key” argument

Callers can set nonce = [OpaqueIidNonce::Random(x)] to pass in a randomly-generated value. This guaranteese the caller similar privacy properties as the original algorithm specified in the RFC without requiring that they keep state in the form of a DAD count.

For fixed inputs, the output of generate_opaque_interface_identifier is guaranteed to be stable across versions this codebase.

pub fn to_be_bytes(&self) -> [u8; 16]

Copies the bytes from this identifier in Big Endian representation.

Trait Implementations

impl Clone for OpaqueIid

fn clone(&self) -> OpaqueIid

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for OpaqueIid

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

Formats the value using the given formatter.

impl Ord for OpaqueIid

fn cmp(&self, other: &OpaqueIid) -> 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 + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for OpaqueIid

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd for OpaqueIid

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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