Struct Sample 

pub struct Sample {
    pub recorded_at: SystemTime,
    pub value: Value,
}

One sample recorded against a (key, scope) bucket.

value is a serde_json::Value so heterogeneous payloads from different writers can share a snapshot reader.

Fields

recorded_at: SystemTime

Wall-clock timestamp the sample was recorded at.

value: Value

Caller-chosen payload.

Implementations

impl Sample

pub fn now(value: Value) -> Self

Record value at SystemTime::now().

pub fn at(when: SystemTime, value: Value) -> Self

Record value at a caller-provided timestamp (for backfilled batches).
