U sP! ) � BinaryReaderaB High-performance binary reader using C implementation.
This reader uses memory-mapped I/O (on Unix) for fast replay of
profiling data from binary files.
Use as a context manager:
with BinaryReader('profile.bin') as reader:
info = reader.get_info()
reader.replay_samples(collector, progress_callback)

This allows converting binary profiling data to other formats
(e.g., flamegraph, pstats) by replaying through the appropriate
collector.
Args:
collector: A Collector instance with a collect() method
progress_callback: Optional callable(current, total) for progress
Returns:
int: Number of samples replayed
