Enum RegistrationObservation 

#[non_exhaustive]
pub enum RegistrationObservation {
    NotRegistered,
    Absent,
    Observed(SocketAddr),
    Invalid(RegistrationObservationError),
}

What the registrar’s top response Via says it observed as this registration’s source.

This is an observation only. It is never copied into Contact, routing, GRUU, Outbound, push, SDP or media policy. Self::Absent and Self::Invalid do not make an otherwise successful registration fail, while Self::NotRegistered says there has not been a successful response to inspect yet.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

NotRegistered

No REGISTER has completed successfully, so there is no response Via to report.

Absent

The top Via was valid and carried neither received nor rport.

Observed(SocketAddr)

The registrar reported one unambiguous IP address and port.

Invalid(RegistrationObservationError)

Observation fields were present but invalid, or the required top Via was unusable.

Implementations

impl RegistrationObservation

pub const fn address(self) -> Option<SocketAddr>

The observed address, only when the registrar stated one unambiguously.

pub fn from_response(response: &Response) -> Self

Interpret the top Via of one successful REGISTER response.

Trait Implementations

impl Clone for RegistrationObservation

fn clone(&self) -> RegistrationObservation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RegistrationObservation

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

Formats the value using the given formatter.

impl Default for RegistrationObservation

fn default() -> RegistrationObservation

Returns the “default value” for a type.

impl PartialEq for RegistrationObservation

fn eq(&self, other: &RegistrationObservation) -> 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.
