A simple string-based template 'language'
This simply allows you to replace ${key} in a string with a 'Val' that impls. std::fmt::Display
use markings::{Args, Template, Opts};
// template strings are simply just ${key} markers in a string
// they are replaced with a cooresponding value when .apply() is used
let input = "hello ${name}, an answer: ${greeting}.";
// parse a template with the default options
// templates are clonable, they are 'consumed' on application.
let template = Template::parse(&input, Opts::default()).unwrap();
// construct some replacement args, this is reusable
let args = Args::new()
// with constructs a key:val pair,
// key must be a &str,
// value is anything that implements std::fmt::Display
.with("name", &"test-user")
.with("greeting", &false);
// apply the pre-computed args to the template, consuming the template
let output = template.apply(&args).unwrap();
assert_eq!(output, "hello test-user, an answer: false.");
