Struct Span 

pub struct Span {
    pub id: String,
    pub conversation_id: String,
    pub kind: String,
    pub name: String,
    pub args_hash: Option<String>,
    pub started_at: i64,
    pub ended_at: Option<i64>,
    pub error: Option<String>,
    pub session_id: Option<String>,
    pub seq: i64,
}

A single ordered span within a run.

Fields

id: String

Stable row id (UUID).

conversation_id: String

The run this span belongs to (conversation_id from the chat request).

kind: String

"tool-call" or "model-call".

name: String

Tool name (tool-call) or model id (model-call).

args_hash: Option<String>

SHA-256 hex of the raw tool-input JSON (tool-call only). Never the raw payload — protects sensitive args from being stored in Core.

started_at: i64

Unix milliseconds — when the span was opened.

ended_at: Option<i64>

Unix milliseconds — when the span was closed. None while in-flight.

error: Option<String>

Error message if the span ended with a failure.

session_id: Option<String>

Nullable link to the gateway audit row via x-ryu-session (populated by #176; None until that thread lands).

seq: i64

Autoincrement ordering key (monotonically increasing within the DB).
