    $validator->field([qw/foo bar baz/]);

DESCRIPTION ^

Field object. Used internally.

ATTRIBUTES ^

deflate

    $field->deflate(sub { s/foo/bar/ });

Use this when you want to change value of field after validation.

inflate

    $field->inflate(sub { s/foo/bar/ });

multiple

    $field->multiple(1);

Field can have multiple values. Use this when you want to allow array reference as a value.

When max value is omitted and is not 1 (because it doesn't make sense), number of values must be equal to this value.
