Enum State 

pub enum State {
    Init,
    Negotiating,
    Ready,
    Disconnected,
    Closing,
    Closed,
}

Session lifecycle state.

The session progresses through these states:

Init ──► Negotiating ──► Ready ──► Closing ──► Closed
             │             │          │
             │             ▼          │
             │       Disconnected ────┴──► Closed
             │             │
             └─────────────┴──────────────► Closed (on error)

Variants

Init

Initial state before negotiation begins.

Negotiating

Handshake in progress (Hello/HelloAck exchange).

Ready

Session is ready for stream operations.

Disconnected

Connection lost but session not yet closed.

The application may attempt to reconnect from this state.

Closing

Graceful shutdown in progress.

Closed

Session has terminated.

Implementations

impl State

pub const fn is_ready(&self) -> bool

Returns true if the session can accept new stream operations.

pub const fn is_closed(&self) -> bool

Returns true if the session has terminated.

pub const fn is_disconnected(&self) -> bool

Returns true if the connection was lost.

pub const fn can_transition_to(&self, target: Self) -> bool

Returns true if a transition to the target state is valid.

Trait Implementations

impl Clone for State

fn clone(&self) -> State

Returns a duplicate 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 Default for State

fn default() -> State

Returns the “default value” for a type.

impl Display for State

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

Formats the value using the given formatter.

impl Hash for State

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 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.

impl Copy for State

impl Eq for State

impl StructuralPartialEq for State
