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:

use file_lookup::home_find_file;

let path = home_find_file("some_file.json").unwrap();

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

use std::path::PathBuf;
use file_lookup::find_file;

let path = find_file("some_file.json", &PathBuf::from("/")).unwrap();

Errors

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

pub enum FileLookupError {
    CwdNotFound,
    HomeDirNotFound,
};
