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 check .

Implementations MAY advertise that they support this interface by returning true for $constraint->DOES("Type::API::Constraint::Coercible") .
