Constructor Detail

def self.new(program : Crystal::Program) #

[View source]
def self.union(program : Program, types : Array(MacroType)) : MacroType #

Returns the union of the given macro types. Additionally reduces the variant types so that:

  • There are no duplicate variant types;
  • NoReturn is not among the variant types, unless the union is empty;
  • No variant type is a subtype of another variant type.

This is analogous to Program#type_merge_union_of for regular types. The returned macro type is a UnionMacroType only if there are 2 or more variant types.

Class Method Detail

def self.subtype?(macro_type : NonGenericMacroType, other : NonGenericMacroType) #

Returns true if macro_type is a subtype of other; that is, every AST node instance of macro_type is also an instance of other.
