NAME

       Type::Tiny::Manual::UsingWithMouse - how to use Type::Tiny and Type::Library with Mouse

SYNOPSIS

          {
             package Person;

             use Mouse;
             use Types::Standard qw( Str Int );

             has name => (
                is      => "ro",
                isa     => Str,
             );

             my $PositiveInt = Int
                -> where( sub { $_ > 0 } )
                -> plus_coercions( Int, sub { abs $_ } );

             has age => (
                is      => "ro",
                isa     => $PositiveInt,
                coerce  => 1,
                writer  => "_set_age",
             );

             sub get_older {
                my $self = shift;
                my ($years) = @_;
                $PositiveInt->assert_valid($years);
                $self->_set_age($self->age + $years);
             }
          }

STATUS

       Mouse support in Type::Tiny was somewhat of an afterthought. It should work, but is not
       anywhere near as well-tested as Moo or Moose support.

DESCRIPTION

       Type::Tiny is tested with Mouse 1.00 and above.

       Type::Tiny type constraints have an API almost identical to that of
       Mouse::Meta::TypeConstraint. As a result, you can use a Type::Tiny object pretty much
       anywhere you'd use a Mouse::Meta::TypeConstraint and you are unlikely to notice the
       difference. (And Mouse is unlikely to notice the difference too!)

   Per-Attribute Coercions
       Type::Tiny offers convenience methods to alter the list of coercions associated with a
       type constraint. Let's imagine we wish to allow our "name" attribute to be coerced from an
       arrayref of strings.

             has name => (
                is      => "ro",
                isa     => Str->plus_coercions(
                   ArrayRef[Str], sub { join " ", @{$_} },
                ),
                coerce  => 1,
             );

       This coercion will apply to the "name" attribute only; other attributes using the "Str"
       type constraint will be unaffected.

       See the documentation for "plus_coercions", "minus_coercions" and "no_coercions" in
       Type::Tiny.

   Optimization
       Mouse's built-in type constraints are implemented using XS and are stupidly fast. For many
       type constraints, if Type::Tiny notices Mouse is loaded early enough, Type::Tiny will
       borrow Mouse's XS subs.

       See also Type::Tiny::Manual::Optimization.

   Interactions with MouseX-Types
       Type::Tiny and MouseX::Types type constraints should "play nice". If, for example,
       "ArrayRef" is taken from Types::Standard (i.e. a Type::Tiny-based type library), and
       "PositiveInt" is taken from MouseX::Types::Common::Numeric, then the following should
       "just work":

          isa => ArrayRef[ PositiveInt ]

          isa => PositiveInt | ArrayRef
