Functions

• compute_crate_hash
  Given a crate name, computes the sha256 hash of its source code (ordered by filename) and returns an hexadecimal string for it.
• compute_dir_filtered_hash
  Given a directory path, computes the sha256 hash of the accumulated contents of all of its files (ordered by filename) except those failing a a custom filter, and returns an hexadecimal string for it.
• compute_dir_hash
  Given a directory path, computes the sha256 hash of the accumulated contents of all of its files (ordered by filename), and returns an hexadecimal string for it.
• compute_file_hash
  Given a file path, computes the sha256 hash of its contents and returns an hexadecimal string for it.
• compute_strings_hash
  Given a bunch of strings, computes the sha256 hash of their contents (in the order they were passed in) and returns an hexadecimal string for it.
• export_build_info_vars_for_crate
  Call from the build.rs file of any crate you want to generate build info for.
• get_and_track_env_var
  Read the environment variable and trigger a rebuild whenever the environment variable changes.
• is_on_ci
  Are we running on a CI machine?
• is_tracked_env_var_set
  Read the environment variable and trigger a rebuild whenever the environment variable changes.
• iter_dir
  Recursively walks the directory at path in filename order.
• read_versioning_hash
  Reads back a versioning hash that was written with write_versioning_hash.
• rebuild_if_crate_changed
  Call from build.rs to trigger a rebuild whenever any source file of the given package or any of its dependencies changes, recursively.
• rerun_if_changed
  Call from build.rs to trigger a rebuild whenever the file at path changes.
• rerun_if_changed_glob
  Call from build.rs to trigger a rebuild whenever any of the files identified by the given globbed path change.
• rerun_if_changed_or_doesnt_exist

• set_output_cargo_build_instructions
  Change whether or not this library should output cargo build instructions
