Struct ReplayRecorder 

pub struct ReplayRecorder { /* private fields */ }

An append-only, capped log of external results for one flow, plus a replay cursor. Recorded during the live run; consumed in order during replay.

Implementations

impl ReplayRecorder

pub fn new() -> Self

A fresh, empty recorder.

pub fn record(&mut self, name: &str, args: &[Value], result: &Value)

Append a recorded external result, respecting RECORDING_CAP. Beyond the cap the result is dropped (replay falls through to fallback).

pub fn take_recorded(&mut self, name: &str, args: &[Value]) -> Option<Value>

Replay-cursor lookup: if the next recorded entry matches name + args, return its result and advance the cursor. On the first mismatch (the program path changed under us) or exhaustion, mark the recorder diverged so every subsequent lookup returns None (→ fallback), rather than feeding misaligned later recordings.

pub fn reset_cursor(&mut self)

Reset the replay cursor and divergence flag to the start of the log, so the recording can drive another replay from the beginning.

pub fn len(&self) -> usize

Number of recorded externals.

pub fn is_empty(&self) -> bool

Whether nothing has been recorded.

Trait Implementations

impl Clone for ReplayRecorder

fn clone(&self) -> ReplayRecorder

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ReplayRecorder

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ReplayRecorder

fn default() -> ReplayRecorder

Returns the “default value” for a type.

impl PartialEq for ReplayRecorder

fn eq(&self, other: &ReplayRecorder) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
