NAME
       Declare::Constraints::Simple::Library::Scalar - Scalar Constraints

SYNOPSIS
	 # match one of a set of regexes
	 my $some_regexes = Matches(qr/foo/, qr/bar/);

	 # allow only defined values
	 my $is_defined = IsDefined;

	 # between 5 and 50 chars
	 my $five_to_fifty = HasLength(5, 50);

	 # match against a set of values
	 my $command_constraint = IsOneOf(qw(create update delete));

	 # check for trueness
	 my $is_true = IsTrue;

	 # simple equality
	 my $is_foo = IsEq('foo');

DESCRIPTION
       This library contains all constraints to validate scalar values.

CONSTRAINTS
   Matches(@regex)
	 my $c = Matches(qr/foo/, qr/bar/);

       If one of the parameters matches the expression, this is true.

   IsDefined()
       True if the value is defined.

   HasLength([$min, [$max]])
       Is true if the value has a length above $min (which defaults to 1> and,
       if supplied, under the value of $max. A simple

	 my $c = HasLength;

       checks if the value has a length of at least 1.

   IsOneOf(@values)
       True if one of the @values equals the passed value. "undef" values work
       with this too, so

	 my $c = IsOneOf(1, 2, undef);

       will return true on an undefined value.

   IsTrue()
       True if the value evulates to true in boolean context.

   IsEq($comparator)
       Valid if the value is "eq" the $comparator.
