Struct SessionSummary 

pub struct SessionSummary {
    pub ulid: String,
    pub started_at_ms: i64,
    pub ended_at_ms: Option<i64>,
    pub engine_base_url: Option<String>,
    pub cli_version: String,
    pub parent_ulid: Option<String>,
    pub n_events: i64,
}

One session row surfaced to the dispatcher. Minimal by design: everything beyond what /sessions renders is looked up on demand through SessionSource::list_events.

Fields

ulid: String

Stable public identifier. What /resume <arg> takes as input and /sessions shows first.

started_at_ms: i64

Epoch milliseconds of started_at. Callers format for display; keeping it as a raw integer means the trait is chrono-free.

ended_at_ms: Option<i64>

Epoch milliseconds of ended_at, or None if the session was interrupted (crash, kill -9). A missing ended_at is load-bearing — it tells the operator a session did not wrap cleanly, which is information they need when deciding whether to /resume or /fork.

engine_base_url: Option<String>

Engine base URL at session start. Surfaced so the operator can spot cross-environment mismatches (“why is this resuming from a paper-trading URL?”) before replaying.

cli_version: String

CLI version string at session start. Same rationale as engine_base_url: out-of-date sessions produce subtle replay surprises and the operator deserves a heads-up.

parent_ulid: Option<String>

Parent ulid when this session was created via /fork. Rendered as a parent:<ulid> tag in the /sessions list.

n_events: i64

Number of events in the session. -1 means the impl could not count cheaply; renderers should omit the count rather than show a lying zero.

Trait Implementations

impl Clone for SessionSummary

fn clone(&self) -> SessionSummary

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SessionSummary

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

Formats the value using the given formatter.

impl PartialEq for SessionSummary

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