gtopt::LpDebugWriter class
#include <gtopt/lp_debug_writer.hpp>

Encapsulates LP debug file writing and optional async gzip compression.

Construct with a non-empty directory to activate. When compression is non-empty and not "uncompressed", each LP file written is gzip- compressed (removing the original .lp). If a pool is provided, compression runs as an async task; otherwise it runs synchronously.

Public functions

auto compress_async(const std::string& lp_path) -> void
auto drain() -> void: Wait for all pending async compression futures.
auto is_active() const -> bool noexcept: Returns true when this writer will actually write files.
auto write(const LinearInterface& li, const std::string& filepath_stem) -> void

Function documentation

void gtopt::LpDebugWriter::compress_async(const std::string& lp_path)

Parameters
lp_path	Full path including `.lp` extension.

Submit gzip compression for an already-written LP file.

void gtopt::LpDebugWriter::write(const LinearInterface& li, const std::string& filepath_stem)

Parameters
li	LP interface whose state to dump.
filepath_stem	Full path stem — extension `.lp` is appended.
