Struct Recorder 

pub struct Recorder { /* private fields */ }

Tracer that builds a TraceTree. The tree is shared via Arc<Mutex> so callers can read it after the VM finishes.

Implementations

impl Recorder

pub fn new() -> Self

pub fn handle(&self) -> Handle

Returned handle stays valid after the tracer is moved into the VM.

pub fn with_overrides(self, overrides: IndexMap<String, Value>) -> Self

Pre-load effect overrides for replay.

Trait Implementations

impl Default for Recorder

fn default() -> Self

Returns the “default value” for a type.

impl Tracer for Recorder

fn enter_call(&mut self, node_id: &str, name: &str, args: &[Value])

fn enter_effect(&mut self, node_id: &str, kind: &str, op: &str, args: &[Value])

fn exit_ok(&mut self, value: &Value)

fn exit_err(&mut self, message: &str)

fn exit_call_tail(&mut self)

Tail-call optimization: pop the current frame’s open call without re-entering the parent (the new call takes its place).

fn override_effect(&mut self, node_id: &str) -> Option<Value>

During replay, return Some(v) to substitute an effect’s output.
