Enum NotificationCode 

pub enum NotificationCode {
    MessageHeader,
    OpenMessage,
    UpdateMessage,
    HoldTimerExpired,
    FsmError,
    Cease,
    Unknown(u8),
}

RFC 4271 §4.5 — NOTIFICATION error codes.

Known codes (1–6) have named variants. Unknown codes from the wire are preserved via Unknown(u8) so the original byte is never lost.

Variants

MessageHeader

Error in the message header (code 1).

OpenMessage

Error in the OPEN message (code 2).

UpdateMessage

Error in the UPDATE message (code 3).

HoldTimerExpired

Hold timer expired without receiving a KEEPALIVE or UPDATE (code 4).

FsmError

Finite state machine error (code 5).

Cease

Administrative or resource-related session termination (code 6).

Unknown(u8)

A code value not defined in RFC 4271. The raw byte is preserved for logging and re-encoding.

Implementations

impl NotificationCode

pub fn from_u8(value: u8) -> Self

Create from a raw code byte, mapping known values to named variants.

pub fn as_u8(self) -> u8

Return the raw byte value for this error code.

Trait Implementations

impl Clone for NotificationCode

fn clone(&self) -> NotificationCode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for NotificationCode

impl Debug for NotificationCode

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

Formats the value using the given formatter.

impl Display for NotificationCode

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

Formats the value using the given formatter.

impl Eq for NotificationCode

impl Hash for NotificationCode

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 PartialEq for NotificationCode

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