Struct SessionStats 

pub struct SessionStats {
    pub total_tool_calls: u32,
    pub total_tokens_saved: u64,
    pub total_tokens_input: u64,
    pub cache_hits: u32,
    pub files_read: u32,
    pub commands_run: u32,
    pub intents_inferred: u32,
    pub intents_explicit: u32,
    pub unsaved_changes: u32,
    pub security: SecurityCounts,
    pub daily: BTreeMap<String, SessionDayCounts>,
    pub client: Option<String>,
}

Aggregate counters for the session: tool calls, token savings, cache hits.

Fields

total_tool_calls: u32

total_tokens_saved: u64

total_tokens_input: u64

cache_hits: u32

files_read: u32

commands_run: u32

intents_inferred: u32

intents_explicit: u32

unsaved_changes: u32

security: SecurityCounts

Security events of this session (display counters; the audit trail is the proof — see lean-ctx value).

daily: BTreeMap<String, SessionDayCounts>

Tool calls and cache hits per UTC day (YYYY-MM-DD), so a session that spans midnight still reports each day’s own counts (Cloud Cockpit metrics). Bounded to the newest SESSION_DAYS_KEPT (120) days.

client: Option<String>

The MCP client that drove this session (its handshake id, e.g. claude-code); None until the first call of a known client.

Implementations

impl SessionStats

pub fn day_mut(&mut self, now: DateTime<Utc>) -> &mut SessionDayCounts

The counters of now’s UTC day, dropping the oldest day once more than SESSION_DAYS_KEPT (120) are held.

Trait Implementations

impl Clone for SessionStats

fn clone(&self) -> Self

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 Default for SessionStats

fn default() -> Self

Returns the “default value” for a type.

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

where SessionStats: Default,

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

where __D: Deserializer<'de>,
