Enum State

#[non_exhaustive]
pub enum State {
    Unknown,
    NotPresent,
    Down,
    LowerLayerDown,
    Testing,
    Dormant,
    Up,
    Other(u8),
}

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

Status can’t be determined

NotPresent

Some component is missing

Down

Down

LowerLayerDown

Down due to state of lower layer

Testing

In some test mode

Dormant

Not up but pending an external event

Up

Up, ready to send packets

Other(u8)

Place holder for new state introduced by kernel when current crate does not support so.

Trait Implementations

impl Clone for State

fn clone(&self) -> State

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for State

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

Formats the value using the given formatter.

impl From<State> for u8

fn from(value: State) -> Self

Converts to this type from the input type.

impl From<u8> for State

fn from(value: u8) -> Self

Converts to this type from the input type.

impl PartialEq for State

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