Enum OperState 

pub enum OperState {
    Unknown,
    NotPresent,
    Down,
    LowerLayerDown,
    Testing,
    Dormant,
    Up,
}

Operational state of a network interface.

This enum models the common states used by Linux and maps equivalent states from other platforms when possible.

Variants

Unknown

Interface state could not be determined.

NotPresent

Interface is not present.

Down

Interface is administratively or otherwise down.

LowerLayerDown

Interface is down because a lower layer is down.

Testing

Interface is in testing state.

Dormant

Interface is dormant.

Up

Interface is operational.

Implementations

impl OperState

pub fn as_str(&self) -> &'static str

Returns the lowercase representation used by Linux operstate files.

pub fn from_if_flags(if_flags: u32) -> Self

Derives an operational state from raw interface flags.

This is used as a fallback when no dedicated operstate API is available. The result is necessarily less precise than native platform state reporting.

Trait Implementations

impl Clone for OperState

fn clone(&self) -> OperState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OperState

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

Formats the value using the given formatter.

impl Display for OperState

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

Formats the value using the given formatter.

impl FromStr for OperState

type Err = ()

The associated error which can be returned from parsing.

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

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

impl Hash for OperState

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 OperState

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