GET /risk summary. Field names mirror the engine’s real wire shape (see engine/zero/api.py::get_risk and the risk.json fixture captured under tests/fixtures/).

Historical note: older mock fixtures used daily_loss_pct, exposure_pct, kill_all, circuit_breaker_active, concurrent_positions, and max_concurrent. The live engine emits none of those; they were removed to stop the CLI from silently rendering — for fields that never existed. Current render code derives percentages from dollar amounts where necessary (see Risk::daily_loss_pct, Risk::drawdown_pct).

extra: BTreeMap<String, Value>

Implementations

impl Risk

pub fn is_halted(&self) -> bool

True when the engine has stopped accepting new risk, for any reason the wire format exposes. The engine currently sets a single halted bool plus a pair of more-specific flags; any of them should land the operator on an alert line.

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

Daily loss as a percent of peak equity, derived from the two dollar fields the engine publishes. Returns None if peak equity is missing or zero so callers can render — rather than a bogus zero.

Trait Implementations

impl Clone for Risk

fn clone(&self) -> Risk

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Risk

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

Formats the value using the given formatter.

impl Default for Risk

fn default() -> Risk

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Risk

where Risk: Default,

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for Risk

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
