Struct TraceSpan 

pub struct TraceSpan {
    pub name: String,
    pub start_time_ms: u64,
    pub end_time_ms: u64,
    pub duration_us: u64,
    pub status: TraceStatus,
    pub attributes: Vec<(String, String)>,
    pub children: Vec<TraceSpan>,
}

A single span in the execution trace.

Shaped to be OTel-compatible: each span has a name, timestamps, status, key-value attributes, and children.

Fields

name: String

Span name (e.g. “parse”, “compile”, “execute”, “tool_call”, “suspend”).

start_time_ms: u64

When the span started (ms since Unix epoch).

end_time_ms: u64

When the span ended (ms since Unix epoch). 0 if still open.

duration_us: u64

Duration in microseconds.

status: TraceStatus

“ok” or “error”.

attributes: Vec<(String, String)>

Structured attributes. Keys use zapcode.* namespace.

children: Vec<TraceSpan>

Child spans.
