Struct ResponseMeta 

pub struct ResponseMeta {
    pub stale: bool,
    pub last_good_at: Option<String>,
    pub last_error: Option<String>,
    pub workspace_state: Option<WorkspaceState>,
    pub daemon_version: String,
}

Metadata attached to every successful response. For Phase 8a management methods the staleness fields are always absent (stale = false, no last_good_at, no last_error, workspace_state = None). Phase 8b populates them from the server-side ServeVerdict for tool-method responses.

Fields

stale: bool

last_good_at: Option<String>

last_error: Option<String>

workspace_state: Option<WorkspaceState>

Canonical workspace state string (serde form of WorkspaceState). None for methods not tied to a workspace.

daemon_version: String

Implementations

impl ResponseMeta

pub fn management(daemon_version: &str) -> Self

Construct the ResponseMeta used by daemon management methods (daemon/status, daemon/unload, daemon/stop — the ones not bound to a specific workspace).

pub fn loaded(daemon_version: &str) -> Self

Construct the ResponseMeta for a successful daemon/load. Phase 8b adds fresh_from / stale_from constructors for MCP tool-method responses that route through classify_for_serve.

pub fn fresh_from(state: WorkspaceState, daemon_version: &str) -> Self

Construct ResponseMeta for a tool-method response served from a Fresh workspace verdict (WorkspaceState::Loaded or Rebuilding).

Phase 8b Task 7 — populated by the tool_dispatch helper when the daemon’s WorkspaceManager::classify_for_serve returns ServeVerdict::Fresh. stale is false and both last_good_at and last_error are absent from the wire form (they are skipped by serde(skip_serializing_if = "Option::is_none")).

pub fn stale_from( last_good_at: SystemTime, last_error: Option<String>, daemon_version: &str, ) -> Self

Construct ResponseMeta for a tool-method response served from a Stale verdict. last_good_at is rendered as RFC3339 UTC-Zulu via chrono::DateTime::<Utc>::from(SystemTime) -> to_rfc3339_opts(Secs, true).

workspace_state is fixed at WorkspaceState::Failed because WorkspaceManager::classify_for_serve only emits a Stale verdict when the observed state is Failed. Keeping this constructor intentionally rigid (no caller-supplied state) prevents the wire form from claiming stale = true with a workspace_state the classifier could never have produced.

Trait Implementations

impl Clone for ResponseMeta

fn clone(&self) -> ResponseMeta

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ResponseMeta

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ResponseMeta

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ResponseMeta

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
