Enum ConnectionState 

#[non_exhaustive]
pub enum ConnectionState {
    Disconnected,
    Connecting,
    Authenticating,
    Configuring,
    Connected,
    Disconnecting,
    Failed,
}

Connection state — the lifecycle of a network connection.

Tier: T2-P (ς State — connection lifecycle)

Disconnected → Connecting → Authenticating → Configuring → Connected
      ↑              │              │              │           │
      └──────────────┴──────────────┴──────────────┴───────────┘
                             (any failure → Disconnected)

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.

Disconnected

Not connected to any network.

Connecting

Attempting to establish link (scanning, associating).

Authenticating

Link established, authenticating (WPA handshake, VPN auth).

Configuring

Authenticated, configuring (DHCP, address assignment).

Connected

Fully connected with IP address and routes.

Disconnecting

Connection is being torn down gracefully.

Failed

Connection failed (transient — will retry or go to Disconnected).

Implementations

impl ConnectionState

pub const fn is_connected(&self) -> bool

Whether this state has network connectivity.

pub const fn is_transitioning(&self) -> bool

Whether a transition is in progress.

pub const fn is_failed(&self) -> bool

Whether this is a terminal failure state.

pub const fn label(&self) -> &'static str

Human-readable label.

Trait Implementations

impl Clone for ConnectionState

fn clone(&self) -> ConnectionState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ConnectionState

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ConnectionState

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for ConnectionState

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 ConnectionState

fn eq(&self, other: &ConnectionState) -> 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 ConnectionState

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for ConnectionState

impl Eq for ConnectionState

impl StructuralPartialEq for ConnectionState
