		# rttc
		Runtime type-checking for JavaScript.

		## Installation

		```sh
		$ npm install rttc --save
		```


		## Legacy Usage

		The usage of this module is changing, but backwards compatibility will be maintained up until the first major version bump (v1.0.0).
		See tests for more details.

		#### rttc.rttc(expectations, inputValues, [options])

		Validate and/or coerce a set of input values against a set of expectations (defined as input definitions.)

		Two options may be provided:
		+ `coerce` - before failing, attempt to coerce not-quite-right input values to their expected type.
		+ `base` - if an input value is missing, fill in its place in the result to the "base type" (falsy value)

		```js
		require('rttc').rttc({
		foo: {
		type: 'string',
		required: true
		},
		bar: {
		type: { baz: {name: 'string'} },
		required: false
		}
		}, {
		foo: 'hi',
		bar: {
		baz: {
		name: 'Rick'
		}
		}
		});
		```

		#### rttc.infer(value)

		Infer the type/schema of the provided value.

		```js
		require('rttc').infer(false);
		// => 'boolean'
		```

		```js
		require('rttc').infer(0);
		// => 'number'
		```

		```js
		require('rttc').infer({
		foo: 'bar'
		});
		// => { foo: 'string' }
		```

		```js
		require('rttc').infer({
		foo: 'whatever',
		bar: { baz: true }
		});
		// => { foo: 'string', bar: { baz: 'boolean' } }
		```

		```js
		require('rttc').infer([{
		foo: ['bar']
		}]);
		// => [{ foo: ['string'] }]
		```

		```js
		require('rttc').infer({
		user: {
		friends: [{
		name: 'Lenny',
		age: 77
		}]
		});
		// =>
		/*
		{
		user: {
		friends: [{
		name: 'Lenny',
		age: 77
		}]
		}
		*/
		```


		#### rttc.types

		```js
		require('rttc').types;

		// =>
		/*

		{ nan: { is: [Function: isNaN], to: [Function] },
		null: { is: [Function: isNull], to: [Function] },
		undefined:
		{ is: [Function: isUndefined],
		to: [Function] },
		bool:
		{ is: [Function: isBoolean],
		to: [Function],
		base: false },
		defined: { is: [Function], to: [Function] },
		int:
		{ is: [Function],
		to: [Function],
		base: 0 },
		str:
		{ is: [Function: isString],
		to: [Function],
		base: '' },
		obj: { is: [Function], to: [Function], base: {} },
		arr:
		{ is: [Function: isArray],
		to: [Function],
		base: [] },
		date:
		{ is: [Function: isDate],
		to: [Function],
		base: Tue Jan 13 2015 08:58:29 GMT-0800 (PST) },
		number:
		{ is: [Function],
		to: [Function],
		base: 0 },
		url:
		{ is: [Function: isString],
		to: [Function],
		base: '' },
		email:
		{ is: [Function: isString],
		to: [Function],
		base: '' },
		string:
		{ is: [Function: isString],
		to: [Function],
		base: '' },
		boolean:
		{ is: [Function: isBoolean],
		to: [Function],
		base: false },
		integer:
		{ is: [Function],
		to: [Function],
		base: 0 },
		float:
		{ is: [Function],
		to: [Function],
		base: 0 } }
		*/
		```
