Struct SimEventLog 

pub struct SimEventLog { /* private fields */ }

Structured event log for a simulation run.

Records every simulated action with monotonic sequence numbers. Two runs with the same seed should produce identical logs — use SimEventLog::diff to verify this and pinpoint the first divergence.

Implementations

impl SimEventLog

pub fn new() -> Self

Create a new, empty event log.

pub fn record( &mut self, timestamp_us: u64, subsystem: Subsystem, description: String, payload: Option<Vec<u8>>, ) -> SeqNo

Record an event. Returns the assigned sequence number.

pub fn record_simple( &mut self, timestamp_us: u64, subsystem: Subsystem, description: impl Into<String>, ) -> SeqNo

Record a simple event (no payload).

pub fn entries(&self) -> &[SimLogEntry]

Get all entries.

pub fn len(&self) -> usize

Number of recorded events.

pub fn is_empty(&self) -> bool

Whether the log is empty.

pub fn diff(a: &SimEventLog, b: &SimEventLog) -> Option<LogDivergence>

Compare two event logs and find the first point of divergence.

Returns None if the logs are identical (same length, same descriptions, same subsystems, same payloads at every sequence number). Returns Some(divergence) with details about where they first differ.

Trait Implementations

impl Default for SimEventLog

fn default() -> Self

Returns the “default value” for a type.
