Type::API::Constraint::Coercible - allows values failing the type constraint to be converted to another value that passes
Implementations of Type::API::Constraint::Coercible MUST also implement Type::API::Constraint.
Implementations MUST provide the following methods:
Returns a boolean indicating whether a coercion is available for this type constraint.
Attempts to coerce the value into a value that would pass the type constraint; this method returns the new value. This method offers no guarantee that the returned value passes the constraint; that must be checked with
Implementations MAY advertise that they support this interface by returning true for
The following CPAN classes are known to implement Type::API::Constraint::Coercible:
Moose::Meta::TypeConstraint (and its subclasses)
Specio::Constraint::Simple (and several other classes in the Specio distribution)
Type::Tiny (and its subclasses)
Some tools can make use of objects implementing Type::API::Constraint::Coercible:
