NetworkManager device state reason codes.

These values come from the NM D-Bus API and indicate why a device transitioned to its current state. Use StateReason::from(code) to convert from the raw u32 values returned by NetworkManager.

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.

Unknown

The reason is unknown.

None

No specific reason given.

UserDisconnected

The user disconnected the device.

DeviceDisconnected

The device was disconnected by the system.

CarrierChanged

The carrier/link status changed (e.g., cable unplugged).

SupplicantDisconnected

The Wi-Fi supplicant disconnected unexpectedly.

SupplicantConfigFailed

The Wi-Fi supplicant’s configuration failed.

SupplicantFailed

The Wi-Fi supplicant failed (authentication issue).

SupplicantTimeout

Trait Implementations

impl Clone for StateReason

fn clone(&self) -> StateReason

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StateReason

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

Formats the value using the given formatter.

impl Display for StateReason

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

Formats the value using the given formatter.

impl From<u32> for StateReason

fn from(code: u32) -> Self

Converts to this type from the input type.

impl PartialEq for StateReason

fn eq(&self, other: &StateReason) -> 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 Copy for StateReason
