Struct Profiler 

pub struct Profiler {
    pub enabled: bool,
    pub events: Vec<(u64, ProfilingEvent)>,
    pub call_stack: Vec<(String, u64)>,
}

Lightweight profiler that records events for later analysis.

Fields

enabled: bool

Whether profiling is currently active.

events: Vec<(u64, ProfilingEvent)>

Recorded events as (timestamp_ns, event) pairs.

call_stack: Vec<(String, u64)>

Stack of (function_name, entry_timestamp_ns) entries.

Implementations

impl Profiler

pub fn new() -> Self

Create a new, disabled profiler.

pub fn enable(&mut self)

Enable profiling.

pub fn disable(&mut self)

Disable profiling.

pub fn record(&mut self, event: ProfilingEvent)

Record an arbitrary profiling event (no-op when disabled).

pub fn enter_function(&mut self, name: &str)

Record a function entry and push it onto the call stack.

pub fn exit_function(&mut self, name: &str)

Record a function exit and pop it from the call stack.

pub fn alloc(&mut self, size: usize, tag: &str)

Record a memory allocation.

pub fn dealloc(&mut self, size: usize, tag: &str)

Record a memory deallocation.

pub fn gc_cycle(&mut self, collected: usize, live: usize)

Record a GC cycle.

pub fn generate_report(&self) -> ProfileReport

Generate a report from the recorded events.

pub fn memory_profile(&self) -> MemoryProfile

Generate a memory profile from the recorded events.

Trait Implementations

impl Default for Profiler

fn default() -> Self
