Fields

seq: u64

Monotonic event number, reset when the trace is cleared.

at_ms: f64

Milliseconds since the trace started (or was last cleared).

kind: JsTraceKind

Event category.

label: String

Short label, e.g. DOMContentLoaded or setTimeout.

detail: String

Human-readable detail: listener counts, URLs, console text, …

duration_us: u64

Execution time in microseconds (0 for instantaneous events).

error: Option<String>

Error message when the event failed.

stack: Vec<String>

JavaScript call stack (innermost first) captured at the event.

source: Option<String>

Bounded source preview for scripts and inline handlers.

source_is_fallback: bool

True when source is the most recently evaluated script, used for callbacks whose VM frame does not retain source text.

variables: Vec<(String, String)>

Local variables captured when this event terminated with an error.

program_counter: Option<usize>

Bytecode program counter captured at a terminal runtime error.
