Enum SessionState 

pub enum SessionState {
    Active,
    Closed,
    Expired,
}

A session’s standing, as every runtime of the mesh reads it. The distinction that matters is between Closed and Expired: the first is a session that said it was finished, the second one whose runtime stopped beating and can no longer say anything. Both end the session’s claims, but only the second is a machine nobody should expect an answer from.

use std::sync::Arc;
use majordomus_cli::mesh::identity::NodeIdentity;
use majordomus_cli::mesh::journal::{EventBody, Journal, SessionInfo, StreamLiveness};
use majordomus_cli::mesh::state::{fold, SessionState};

let j = Journal::open(Arc::new(NodeIdentity::ephemeral().unwrap()), "0000000000000001",
    "repo".into(), None).unwrap();
j.append_own(EventBody::SessionOpened { info: SessionInfo::named("s1", "cli") }).unwrap();
assert_eq!(fold(&j.events(), &|_| StreamLiveness::Own).sessions[0].state, SessionState::Active);

// the same events, read on a runtime that no longer hears the writer
let gone = fold(&j.events(), &|_| StreamLiveness::Expired);
assert_eq!(gone.sessions[0].state, SessionState::Expired);

Variants

Active

Open, and its runtime is alive.

Closed

Closed by its own runtime.

Expired

Never closed, but its runtime stopped beating: gone, as far as anyone can tell.

Trait Implementations

impl Clone for SessionState

fn clone(&self) -> SessionState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for SessionState

impl Debug for SessionState

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SessionState

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for SessionState

impl JsonSchema for SessionState

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl PartialEq for SessionState

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
