Clarification on dry-types support in dry-schema

Support
1

According to the web documentation:

The DSL accepts any Dry::Types::Type object

I have a type defined simliar to this:

module Types
  include Dry::Types(default: :nominal)

  Metadata = Strict::Hash.optional
  Href = Strict::String | Hash.schema(href: Strict::String, meta: Metadata)
  Links = Map(Symbol, Href)
end

I’m defining a schema as the docs suggest:

schema = Dry::Schema.JSON do
  required(:links).value(Types::Links)
end

which results in this error:

NoMethodError: undefined method `visit_map' for #<Dry::Schema::PredicateInferrer::Compiler:0x00007ff619665500>

What am I doing wrong here?

2

Types::Map is not supported yet. In order to make it work we need to add support for validating keys.

3

Is there documentation anywhere about which types are supported and which aren’t?

I think I’m going to have to ditch dry-types here and try something else. :thinking: What if I wrote reusable dry-logic predicates in place of my types… would that work?
