Struct StateSnapshot 

pub struct StateSnapshot {
    pub user_id: String,
    pub updated_at_unix_ms: i64,
    pub source: Source,
    pub confidence: f32,
    pub axes: BTreeMap<String, f32>,
}

A snapshot of user state at a point in time.

State is represented as values along named axes, where each axis is a value in [0.0, 1.0] with defined semantics.

PII Redaction

The Debug implementation redacts the user_id field to prevent accidental logging of personally identifiable information. Only the first 4 characters are shown, followed by ....

Fields

user_id: String

Unique identifier for the user.

updated_at_unix_ms: i64

Unix timestamp in milliseconds when this snapshot was created/updated.

source: Source

How this state was obtained.

confidence: f32

Confidence in the accuracy of this snapshot [0.0, 1.0].

axes: BTreeMap<String, f32>

Axis values as a map from axis name to value. Values must be in [0.0, 1.0].

Implementations

impl StateSnapshot

pub fn builder() -> StateSnapshotBuilder

Create a new builder for constructing a StateSnapshot.

pub fn validate(&self) -> Result<(), ValidationError>

Validate the snapshot, returning errors if invalid.

pub fn get_axis(&self, name: &str) -> f32

Get an axis value, returning the default (0.5) if not present.

pub fn get_axis_opt(&self, name: &str) -> Option<f32>

Get an axis value if present.
