Enum CarrierState 

#[repr(u8)]
pub enum CarrierState {
    unknown = 0,
    off = 1,
    no_carrier = 2,
    dormant = 3,
    degraded_carrier = 4,
    carrier = 5,
    enslaved = 6,
}

Physical carrier (link layer) state of a networkd-managed interface. Ref: https://github.com/systemd/systemd/blob/main/src/libsystemd/sd-network/network-util.h

Variants

unknown = 0

Carrier state could not be determined

off = 1

Interface is administratively down (IFF_UP not set)

no_carrier = 2

Interface is up but no carrier signal detected (cable unplugged or no link partner)

dormant = 3

Carrier detected but interface is in a dormant/standby state

degraded_carrier = 4

Carrier detected but in a degraded condition

carrier = 5

Full carrier signal present and link is operational

enslaved = 6

Interface is enslaved to a bond/bridge master

Trait Implementations

impl Clone for CarrierState

fn clone(&self) -> CarrierState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CarrierState

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

Formats the value using the given formatter.

impl Default for CarrierState

fn default() -> CarrierState

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for CarrierState

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for CarrierState

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

Formats the value using the given formatter.

impl From<CarrierState> for u8

fn from(v: CarrierState) -> Self

Converts to this type from the input type.

impl FromStr for CarrierState

type Err = ParseError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<CarrierState, <Self as FromStr>::Err>

Parses a string s to return a value of this type.

impl IntoEnumIterator for CarrierState

type Iterator = CarrierStateIter

fn iter() -> CarrierStateIter

impl PartialEq for CarrierState

fn eq(&self, other: &CarrierState) -> 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 Serialize for CarrierState

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<&str> for CarrierState

type Error = ParseError

The type returned in the event of a conversion error.

fn try_from(s: &str) -> Result<CarrierState, <Self as TryFrom<&str>>::Error>

Performs the conversion.

impl TryFrom<u8> for CarrierState

type Error = u8

The type returned in the event of a conversion error.

fn try_from(v: u8) -> Result<Self, u8>

Performs the conversion.

impl Copy for CarrierState

impl Eq for CarrierState

impl StructuralPartialEq for CarrierState
