Struct Record 

pub struct Record {
    pub ts: u64,
    pub event: String,
    pub data: Value,
}

A timestamped record in the JSONL session file.

Records use internal tagging to distinguish event types while maintaining a flat structure for easy parsing.

Fields

ts: u64

Unix timestamp in milliseconds when the event was recorded.

event: String

The event type discriminator (e.g., “bus.publish”, “ux.terminal.write”).

data: Value

The event data, serialized based on event type.

Implementations

impl Record

pub fn new(event: impl Into<String>, data: impl Serialize) -> Self

Creates a new record with the current timestamp.

pub fn from_bus_event(event: &Event) -> Self

Creates a record for an EventBus event.

pub fn from_ux_event(ux_event: &UxEvent) -> Self

Creates a record for a UX event.

pub fn meta_loop_start( prompt_file: &str, max_iterations: u32, ux_mode: Option<&str>, ) -> Self

Creates a metadata record for loop start.

pub fn meta_iteration(iteration: u32, elapsed_ms: u64, hat: &str) -> Self

Creates a metadata record for an iteration.

pub fn meta_termination( reason: &str, iterations: u32, elapsed_secs: f64, ux_writes: u32, ) -> Self

Creates a metadata record for termination.
