pub fn find_program_in_path(program: impl AsRef<Path>) -> Option<PathBuf>Expand description
Locates the first executable named @program in the user’s path, in the
same way that execvp() would locate it. Returns an allocated string
with the absolute path name, or None if the program is not found in
the path. If @program is already an absolute path, returns a copy of
@program if @program exists and is executable, and None otherwise.
On Windows, if @program does not have a file type suffix, tries
with the suffixes .exe, .cmd, .bat and .com, and the suffixes in
the PATHEXT environment variable.
On Windows, it looks for the file in the same way as CreateProcess()
would. This means first in the directory where the executing
program was loaded from, then in the current directory, then in the
Windows 32-bit system directory, then in the Windows directory, and
finally in the directories in the PATH environment variable. If
the program is found, the return value contains the full name
including the type suffix.
