sU sP! )�BinaryCollectora1 High-performance binary collector using C implementation.
This collector writes profiling data directly to a binary file format
with optional zstd compression. All I/O is performed in C for maximum
throughput.
The binary format uses string/frame deduplication and varint encoding
for efficient storage.

Args:

skip_idle: If True, skip idle threads (not used in binary format)
compression: 'auto', 'zstd', 'none', or int (0=none, 1=zstd)

This passes stack_frames directly to the C writer which handles
all encoding and buffering.
Args:
stack_frames: List of InterpreterInfo objects from _remote_debugging
timestamp_us: Optional timestamp in microseconds. If not provided,
uses time.monotonic() to generate one.
