Struct RegId 

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

Which flow a registration is for (§4.2).

One reg-id per flow, and the same number when that flow is refreshed or re-established — which is what tells the registrar “this replaces the binding for flow 2” rather than “here is another contact”. §4.2 also requires the sequence to be stable across reboots, so these are numbered from the outbound proxy set’s order rather than allocated as flows come up.

Implementations

impl RegId

pub fn new(value: u32) -> Option<Self>

A reg-id, if the value is one RFC 5626 §4.2 permits.

Zero is excluded by the RFC explicitly. That is not pedantry: a registrar that receives reg-id=0 is entitled to reject the registration, and the failure looks like a credentials problem rather than an off-by-one.

pub fn value(self) -> u32

The number.

Trait Implementations

impl Clone for RegId

fn clone(&self) -> RegId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RegId

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

Formats the value using the given formatter.

impl Ord for RegId

fn cmp(&self, other: &RegId) -> 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 RegId

fn eq(&self, other: &RegId) -> 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 RegId

fn partial_cmp(&self, other: &RegId) -> 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.
