Struct AppStateSnapshot 

pub struct AppStateSnapshot {
    pub session_id: String,
    pub message_count: usize,
    pub last_tool_results: Vec<ToolResultEntry>,
    pub snapshot_timestamp_ms: u64,
    pub completed: bool,
    pub project_dir: String,
    pub cost_usd: f64,
}

Essential application state that is persisted for crash recovery.

Fields

session_id: String

The active session ID.

message_count: usize

Number of messages exchanged so far.

last_tool_results: Vec<ToolResultEntry>

Last tool results (tool name -> truncated output), limited to most recent.

snapshot_timestamp_ms: u64

Timestamp (ms since epoch) when the snapshot was taken.

completed: bool

Whether the session ended cleanly.

project_dir: String

Project directory associated with the session.

cost_usd: f64

Cumulative cost in USD.

Implementations

impl AppStateSnapshot

pub fn new( session_id: impl Into<String>, project_dir: impl Into<String>, ) -> Self

Create a new snapshot with the given session ID.

pub fn record_tool_result(&mut self, entry: ToolResultEntry, max_entries: usize)

Record a tool result. Keeps at most max_entries most recent results.

pub fn mark_completed(&mut self)

Mark the session as completed (clean exit).

Trait Implementations

impl Clone for AppStateSnapshot

fn clone(&self) -> AppStateSnapshot

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AppStateSnapshot

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for AppStateSnapshot

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for AppStateSnapshot

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
