Struct SessionStats 

pub struct SessionStats {
    pub session_id: Uuid,
    pub message_count: u64,
    pub tool_call_count: u64,
    pub tool_success_count: u64,
    pub tool_failure_count: u64,

    pub total_output_tokens: u64,
    pub total_tokens: u64,
    pub avg_tool_duration_ms: u64,
}

Pre-computed or live-aggregated statistics for a session.

Provides a summary view including message count, tool execution counts (total / success / failure), cumulative token usage, and average tool execution duration.

Fields

session_id: Uuid

Session identifier.

message_count: u64

Total number of messages in the session.

tool_call_count: u64

Total number of tool executions.

tool_success_count: u64

Number of successful tool executions.

tool_failure_count: u64

Number of failed tool executions.

total_input_tokens: u64

Cumulative input tokens across all provider calls.

total_output_tokens: u64

Cumulative output tokens across all provider calls.

total_tokens: u64

Cumulative total tokens.

avg_tool_duration_ms: u64

Average tool execution duration in milliseconds.

Implementations

impl SessionStats

pub fn empty(session_id: Uuid) -> Self

Creates an all-zero stats struct for a session.

All counters and the average duration are initialized to zero.

Trait Implementations

impl Clone for SessionStats

fn clone(&self) -> SessionStats

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SessionStats

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SessionStats

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for SessionStats

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
