Fields

schema: u32

session_id: String

project_root: Option<String>

started_at: Option<DateTime<Utc>>

updated_at: Option<DateTime<Utc>>

tool_calls: u64

tokens_input: u64

Tokens lean-ctx’s tools would have sent without compression.

tokens_saved: u64

Tokens kept out of the model’s context (measured, per tool result).

cache_hits: u64

files_read: u64

commands_run: u64

security: SecurityCounts

host_pid: Option<u32>

The agent process that started the writing MCP server (see super::host).

Implementations

impl ValueSnapshot

pub fn from_session(session: &SessionState) -> Self

pub fn saved_pct(&self) -> Option<f64>

Share of tool input kept out of context, in percent (derived).

pub fn is_fresh(&self, max_age: Duration) -> bool

True when the snapshot was updated within max_age. Display channels show nothing for a stale snapshot — never a misleading old number.

pub fn is_empty(&self) -> bool

Nothing worth showing yet.

Trait Implementations

impl Clone for ValueSnapshot

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 ValueSnapshot

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

Formats the value using the given formatter.

impl Default for ValueSnapshot

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ValueSnapshot

where ValueSnapshot: Default,

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

where __D: Deserializer<'de>,
