Struct Session 

pub struct Session {
    pub id: String,
    pub agent: String,
    pub project: Option<String>,
    pub model: Option<String>,
    pub parent_session: Option<String>,
    pub started_at: Option<Timestamp>,
    pub ended_at: Option<Timestamp>,
    pub events: Vec<Event>,
    pub sub_agents: Vec<SubAgent>,
    pub skipped_lines: u64,
}

One normalized agent conversation/run.

Fields

id: String

agent: String

project: Option<String>

model: Option<String>

Most frequently seen (non-synthetic) assistant model, if any.

parent_session: Option<String>

For sub-agent transcripts (e.g. Claude Code’s <project>/<parent-session-uuid>/subagents/agent-*.jsonl): the parent session id this spend is attributed to (CLAUDE.md §8.3).

started_at: Option<Timestamp>

ended_at: Option<Timestamp>

events: Vec<Event>

sub_agents: Vec<SubAgent>

Sub-agents spawned BY this session (Task/Agent tool calls).

skipped_lines: u64

Lines that failed to parse or had an unrecognized shape. Skipped leniently, surfaced so format drift is visible instead of silent.

Trait Implementations

impl Clone for Session

fn clone(&self) -> Session

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Session

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Session

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Session

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
