use Venus::Type;

my $type = Venus::Type->new(value => {});

my $code = $type->code;

# "HASH"

code example 3

package main;

use Venus::Type;

my $type = Venus::Type->new(value => qr//);

my $code = $type->code;

# "REGEXP"

deduce

deduce() (Object)

The deduce methods returns the argument as a data type object.

Since 0.01

deduce example 1

my $deduce = $type->deduce;

# bless({ value => {} }, "Venus::Hash")

deduce example 3

package main;

use Venus::Type;

my $type = Venus::Type->new(value => qr//);

my $deduce = $type->deduce;

# bless({ value => qr// }, "Venus::Regexp")

deduce example 4

package main;

my $type = Venus::Type->new(value => '1.23');

my $deduce = $type->deduce;

# bless({ value => "1.23" }, "Venus::Float")

deduce_deep

deduce_deep() (Object)

The deduce_deep function returns any arguments as data type objects, including nested data.

my $deduce_deep = $type->deduce_deep;

# bless({
#   value => [
#     bless({ value => 1 }, "Venus::Number"),
#     bless({ value => 2 }, "Venus::Number"),
#     bless({ value => 3 }, "Venus::Number"),
#     bless({ value => 4 }, "Venus::Number"),
#   ],
# }, "Venus::Array")

deduce_deep example 2

package main;

use Venus::Type;

my $type = Venus::Type->new(value => {1..4});

my $deduce_deep = $type->deduce_deep;

# bless({
#   value => {
#     1 => bless({ value => 2 }, "Venus::Number"),
#     3 => bless({ value => 4 }, "Venus::Number"),
#   },
# }, "Venus::Hash")

detract

detract() (Any)

The detract method returns the argument as native Perl data type value.

Since 0.01

detract example 1

package main;

use Venus::Type;
use Venus::Hash;

my $type = Venus::Type->new(Venus::Hash->new({1..4}));

my $detract = $type->detract;

# { 1 => 2, 3 => 4 }

detract example 2

package main;

use Venus::Type;
use Venus::Array;

my $type = Venus::Type->new(Venus::Array->new([1..4]));

my $detract = $type->detract;

# [1..4]

detract example 3

package main;

use Venus::Type;
use Venus::Regexp;

my $type = Venus::Type->new(Venus::Regexp->new(qr/\w+/));

my $detract = $type->detract;

# qr/\w+/

detract example 4

package main;

use Venus::Type;
use Venus::Float;

my $type = Venus::Type->new(Venus::Float->new('1.23'));

my $detract = $type->detract;

# "1.23"

detract_deep

detract_deep() (Any)

The detract_deep method returns any arguments as native Perl data type values, including nested data.

Since 0.01

detract_deep example 1

package main;

use Venus::Type;
use Venus::Hash;

my $type = Venus::Type->new(Venus::Hash->new({1..4}));

my $detract_deep = Venus::Type->new($type->deduce_deep)->detract_deep;

# { 1 => 2, 3 => 4 }

detract_deep example 2

package main;

use Venus::Type;
use Venus::Array;

my $type = Venus::Type->new(Venus::Array->new([1..4]));

my $detract_deep = Venus::Type->new($type->deduce_deep)->detract_deep;

# [1..4]

package

package() (Str)

The code method returns the package name of the objectified value, i.e. ref().

Since 0.01

package example 1

# given: synopsis;

my $package = $type->package;

# "Venus::Array"
