=head1 NAME

Types::Common::String - drop-in replacement for MooseX::Types::Common::String

=head1 STATUS

This module is covered by the
L<Type-Tiny stability policy|Type::Tiny::Manual::Policies/"STABILITY">.

=head1 DESCRIPTION

A drop-in replacement for L<MooseX::Types::Common::String>.

=head2 Types

The following types are similar to those described in
L<MooseX::Types::Common::String>.

=over

=item *

B<SimpleStr>

=item *

B<NonEmptySimpleStr>

=item *

B<NumericCode>

=item *

B<LowerCaseSimpleStr>

=item *

B<UpperCaseSimpleStr>

=item *

B<Password>

=item *

B<StrongPassword>

=item *

B<NonEmptyStr>

=item *

B<LowerCaseStr>

=item *

B<UpperCaseStr>

=back

This module also defines an extra type constraint not found in
L<MooseX::Types::Common::String>.

=over

=item *

B<< StrLength[`min, `max] >>

Type constraint for a string between min and max characters long. For
example:

  StrLength[4, 20]

It is sometimes useful to combine this with another type constraint in an
intersection.

  (LowerCaseStr) & (StrLength[4, 20])

The max length can be omitted.

  StrLength[10]   # at least 10 characters

Lengths are inclusive.

=head1 BUGS
