Struct LogLine 

pub struct LogLine {
    pub ts_ns: u64,
    pub severity: LogSeverity,
    pub service: String,
    pub message: String,
    pub labels: HashMap<String, String>,
    pub numeric_fields: HashMap<String, f64>,
    pub trace_id: Option<String>,
    pub span_id: Option<String>,
}

One structured log line. labels is the low-cardinality map (service, region, severity_str); fields carries typed extra payload (latency_ms, status, bytes_out). Keeping them separate lets the codec layer pick Dict for labels and T64 / Delta for numeric fields.

Fields

ts_ns: u64

severity: LogSeverity

service: String

message: String

labels: HashMap<String, String>

numeric_fields: HashMap<String, f64>

trace_id: Option<String>

Optional trace / span identifiers — wiring for graph-based span traversal comes later; the field lives here so the ingest pipe doesn’t need to reshape when that lands.

span_id: Option<String>

Implementations
