Struct CursorRow 

pub struct CursorRow {
    pub source_name: String,
    pub value: Option<Value>,
    pub version: i64,
    pub updated_at: String,
    pub age_seconds: f64,
}

One _fraiseql_source_cursor row: a source’s durable watermark and its staleness, computed against the database clock so there is no app↔DB skew.

Fields

source_name: String

The cursor key — the source name the runtime poller advances under.

value: Option<Value>

The opaque cursor value, or None if the row exists but holds SQL NULL.

version: i64

The compare-and-swap generation counter.

updated_at: String

Last-advance timestamp, rendered as text (updated_at::text).

age_seconds: f64

Seconds since the last advance, from the database clock (the staleness/lag).
