Module tracked
Functionality for adding environment state to the build dependency info.
Functions
-
env_var
Retrieve an environment variable and add it to build dependency info.
The build system executing the compiler will know that the variable was accessed during
compilation, and will be able to rerun the build when the value of that variable changes.
Besides the dependency tracking this function should be equivalent to
env::varfrom the standard library, except that the argument must be UTF-8. - path Track a file or directory explicitly.
