NAME
    Class::Tiny::ConstrainedAccessor - Generate Class::Tiny accessors that
    apply type constraints

    Class::Tiny uses custom accessors if they are defined before the "use
    Class::Tiny" statement in a package.  This module creates custom accessors
    that behave as standard "Class::Tiny" accessors except that they apply
    type constraints ("isa" relationships).  Type constraints can come from
    Type::Tiny, MooseX::Types, MooX::Types::MooseLike, MouseX::Types, or
    Specio.

    Example of a class using this package:

        package SampleClass;
        use Scalar::Util qw(looks_like_number);

        use Type::Tiny;

        my $MediumInteger;
        BEGIN {
            # Create the type constraint
            $MediumInteger = Type::Tiny->new(
                name => 'MediumInteger',
                constraint => sub { looks_like_number($_) and $_ >= 10 and $_ < 20 }
            );
        }

        use Class::Tiny::ConstrainedAccessor {
            medint => $MediumInteger,           # create accessor sub medint()
            med_with_default => $MediumInteger,
        };

        # After using ConstrainedAccessor, actually define the class attributes.
        use Class::Tiny qw(medint regular), {
            med_with_default => 12,
        };

SUBROUTINES
  import
    Creates the accessors you have requested.  Usage:

        use Class::Tiny::ConstrainedAccessor
            [optional arrayref of option=>value],
            name => constraint
            [, name => constraint]...  ;

    The options use an arrayref to make them stand out against the
    "name=>constraint" pairs that come after.

    This also creates a "BUILD" in Class::Tiny to check the constructor
    parameters if one doesn't exist.  If one does exist, it creates the same
    function as "_check_all_constraints" so that you can call it from your own
    BUILD.  It takes the same parameters as "BUILD".

OPTIONS
    Remember, options are carried in an arrayref.  This is to leave room for
    someday carrying attributes and constraints in a hashref.

    NOBUILD
        If "NOBUILD => 1" is given, the constructor-parameter-checker is
        created as "_check_all_constraints" regardless of whether "BUILD()"
        exists or not.  Example:

            package MyClass;
            use Class::Tiny::ConstrainedAccessor
                [NOBUILD => 1],
                foo => SomeConstraint;
