Received SNMP notification.

This enum represents all types of SNMP notifications that can be received:

• SNMPv1 Trap (different PDU structure)
• SNMPv2c/v3 Trap (standard PDU with sysUpTime.0 and snmpTrapOID.0)
• InformRequest (confirmed notification, response will be sent automatically)

Implementations

impl Notification

pub fn trap_oid(&self) -> Result<Oid>

Get the trap/notification OID.

For TrapV1, this is derived from enterprise + generic/specific trap. For v2c/v3, this is the snmpTrapOID.0 value.

pub fn uptime(&self) -> u32

Get the uptime value (sysUpTime.0 or time_stamp for v1).

pub fn varbinds(&self) -> &[VarBind]

Get the variable bindings.

pub fn is_confirmed(&self) -> bool

Check if this is a confirmed notification (InformRequest).

pub fn version(&self) -> Version

Get the SNMP version of this notification.

Trait Implementations

impl Clone for Notification

fn clone(&self) -> Notification

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Notification

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

Formats the value using the given formatter.
