file_lookup

For when you want to look up from the current working directory for a file by name.

Example Usage

Find a file within your home directory, looking up from your current working directory:

```rust use filelookup::homefind_file;

let path = homefindfile("some_file.json").unwrap(); ```

Find a file within your root directory (or anyhwere else), looking up from your current working directory:

```rust use std::path::PathBuf; use filelookup::findfile;

let path = findfile("somefile.json", &PathBuf::from("/")).unwrap(); ```

Errors

These functions fail if there is a failure to ascertain your current working directory or your home directory:

rust pub enum FileLookupError { CwdNotFound, HomeDirNotFound, };
