Function traverse

pub fn traverse<E: Debug + Display + StdError>(
    src: impl AsRef<Path>,
    dest: impl AsRef<Path>,
    transform_path: impl Fn(&Path) -> Result<PathBuf, E>,
    template_ext: Option<&str>,
) -> Result<VecDeque<Action>, TraversalError<E>>

Traverse file tree at src to generate an Action list. The Action list specifies how to generate the src file tree at dest, and can be executed by Bicycle::process_actions.

File tree contents are interpreted as follows:

• Each directory in the file tree generates an Action::CreateDirectory. Directories are traversed recursively.
• Each file that doesn’t end in template_ext generates an Action::CopyFile.
• Each file that ends in template_ext generates an Action::WriteTemplate.

transform_path is used to post-process destination path strings. Bicycle::transform_path is one possible implementation.
