Enum ConnectionState 

#[non_exhaustive]
pub enum ConnectionState {
    Disconnected,
    Connecting,
    Connected,
    Error,
}

Lifecycle state of a Client connection to the CLI.

The state advances from Connecting → Connected during construction, transitions to Disconnected after Client::stop or Client::force_stop, and lands in Error if startup fails or the underlying transport tears down unexpectedly.

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

No CLI process is attached or the process has exited cleanly.

Connecting

The client is starting up (spawning the CLI, negotiating protocol).

Connected

The client is connected and ready to handle RPC traffic.

Error

Startup failed or the connection encountered an unrecoverable error.

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
