Struct Snapshot 

pub struct Snapshot {
    pub label: Label,
    pub friction: FrictionLevel,
    pub vector: StateVector,
    pub as_of: DateTime<Utc>,
    pub version: u64,
}

Cheap, clone-safe summary consumed by the TUI.

Fields

label: Label

friction: FrictionLevel

vector: StateVector

as_of: DateTime<Utc>

When this snapshot was produced.

version: u64

Monotonic version number; widgets compare to their last seen and skip render when equal.

Implementations

impl Snapshot

pub fn new( label: Label, vector: StateVector, as_of: DateTime<Utc>, version: u64, ) -> Self

Construct a snapshot whose friction is derived from label alone. Caps at L2 — call Snapshot::new_with_risk from a caller with engine access to reach L3/L4.

pub fn new_with_risk( label: Label, vector: StateVector, as_of: DateTime<Utc>, version: u64, risk: RiskContext, ) -> Self

Construct a snapshot whose friction is derived from both label and the engine-reported risk.

This is the M2 entrypoint. It uses FrictionLevel::from_label_and_risk so the snapshot’s .friction field can reach L3 (TILT + guardrail proximity) or L4 (TILT + halt). Callers without engine context (tests, pure replay, the classifier’s default classify path) stay on Self::new and retain the L2 cap.

Trait Implementations

impl<'de> Deserialize<'de> for Snapshot

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for Snapshot

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

where __S: Serializer,
