Struct PrintTracer 

pub struct PrintTracer<'s> { /* private fields */ }

Tracer that collects execution trace for debugging.

Implementations

impl<'s> PrintTracer<'s>

pub fn builder<'m>( source: &'s str, module: &'m Module, ) -> PrintTracerBuilder<'s, 'm>

Create a builder for PrintTracer.

pub fn print(&self)

Print all trace lines.

Trait Implementations

impl Tracer for PrintTracer<'_>

fn trace_instruction(&mut self, ip: u16, instr: &Instruction<'_>)

Called before executing an instruction.

fn trace_nav(&mut self, nav: Nav, node: Node<'_>)

Called after navigation succeeds.

fn trace_nav_failure(&mut self, nav: Nav)

Called when navigation fails (no child/sibling exists).

fn trace_match_success(&mut self, node: Node<'_>)

Called after type check succeeds.

fn trace_match_failure(&mut self, node: Node<'_>)

Called after type check fails.

fn trace_field_success(&mut self, field_id: NonZero<u16>)

Called after field check succeeds.

fn trace_field_failure(&mut self, _node: Node<'_>)

Called after field check fails.

fn trace_effect(&mut self, effect: &RuntimeEffect<'_>)

Called after emitting an effect.

fn trace_effect_suppressed(&mut self, opcode: EffectOpcode, payload: usize)

Called when an effect is suppressed (inside @_ capture).

fn trace_suppress_control(&mut self, opcode: EffectOpcode, suppressed: bool)

Called for SuppressBegin/SuppressEnd control effects. suppressed is true if already inside another suppress scope.

fn trace_call(&mut self, target_ip: u16)

Called when entering a definition via Call.

fn trace_return(&mut self)

Called when returning from a definition.

fn trace_checkpoint_created(&mut self, ip: u16)

Called when a checkpoint is created.

fn trace_backtrack(&mut self)

Called when backtracking occurs.

fn trace_enter_entrypoint(&mut self, target_ip: u16)

Called when entering an entrypoint (for section labels).

fn trace_enter_preamble(&mut self)

Called when entering the preamble (bootstrap wrapper).
