Structs

• TimeIt

Functions

  Copied from std::path::absolute until it stabilizes.
• absolute_unix 🔒
  Make a POSIX path absolute without changing its semantics.

• add_link_lib_path
  Adds a list of lookup paths to cmd’s link library lookup path.
• check_run
• dir_is_empty
• dir_up_to_date 🔒
• dylib_path
  Parses the dylib_path_var() environment variable, returning a list of paths that are members of this lookup path.
• dylib_path_var
  Returns the environment variable which the dynamic library lookup path resides in for this platform.
• exe
  Given an executable called name, return the filename for the executable for a particular target.
• forcing_clang_based_tests
• get_clang_cl_resource_dir

• is_debug_info
  Returns true if the file name given looks like a debug info file
• is_dylib
  Returns true if the file name given looks like a dynamic library.
• is_valid_test_suite_arg
• libdir
  Returns the corresponding relative library directory that the compiler’s dylibs will be found in.
• link_lib_path 🔒
  Parses the link_lib_path_var() environment variable, returning a list of paths that are members of this lookup path.
• link_lib_path_var 🔒
  Returns the environment variable which the link library lookup path resides in for this platform.
• lld_flag_no_threads
• make
• mtime
  Returns the last-modified time for path, or zero if it doesn’t exist.
• output
• output_result
• program_out_of_date 🔒
  Used for download caching
• run
• run_suppressed
• symlink_dir
  Symlinks two directories, using junctions on Windows and normal symlinks on Unix.
• timeit
  Returns an RAII structure that prints out how long it took to drop.
• try_run_suppressed
• up_to_date
  Returns true if dst is up to date given that the file or files in src are used to generate it.
• use_host_linker
