Struct FieldRow 

pub struct FieldRow {
    pub key: String,
    pub path: String,
    pub seen: u64,
    pub documents: u64,
    pub kinds: Vec<String>,
    pub changes: u64,
    pub last_change_s: Option<f64>,

    pub last: Option<f64>,
    pub values: Option<Vec<String>>,
}

One dotted path’s statistics over a zenctl field window (#223) — the per-field arrival story validation cannot tell.

Fields

key: String

The concrete wire key the path was observed under.

path: String

The dotted path inside the structural value ($ = a non-object root).

seen: u64

Document samples in which the path was present.

documents: u64

The key’s document samples — the presence ratio’s denominator.

kinds: Vec<String>

JSON kinds observed (one entry = type-stable).

changes: u64

Times the value differed from its previous observation.

last_change_s: Option<f64>

Window-relative seconds of the last change; absent = never changed within the window (which the stated window scopes — not “never”).

min: Option<f64>

Numeric min/max/last, present only when the path carried numbers.

max: Option<f64>

last: Option<f64>

values: Option<Vec<String>>

Small-domain distinct values, total when present; absent = the domain outgrew the cap (stated, never silently partial).
