Declare::Constraints::Simple::Library::Exportable - Export Facilities
This contains the constraint export logic of the module.
use ExportableModule->All; # or use ExportableModule-Only => qw(Constraint1 ...); # or use ExportableModule-Library;
Exports the constraints to the calling namespace. This includes all libraries in Declare::Constraints::Simple::Library, that package itself (providing all default constraints) or Declare::Constraints::Simple itself as a shortcut.
Possible flags are
Imports all constraints registered in the class and its base classes.
use Declare::Constraints::Simple::Library::Scalar-Only => 'HasLength';
The above line would only import the HasLength
constraints from the Scalar
default library. Note however, that you could also just have said
use Declare::Constraints::Simple-Only => 'HasLength';
as both ::Simple
and ::Simple::Library
work on all default libraries.
You can use this to define your own constraint library. For more information, see Declare::Constraints::Simple::Library::Base.
Internal method to build constraint-to-class mappings.
Internal method. Exports all handles in $handle_map
into the $target
namespace.
Internal method. Exports all @constraints
