Instance Method Detail

def name : PathSource

Returns the path to the generic.

def named_args : NamedTupleLiteral | NilLiteralSource

Returns the named arguments of this instantiation, if any.

def resolve : ASTNodeSource

Resolves this generic to a TypeNode if it denotes a type, or otherwise gives a compile-time error.

def resolve? : ASTNode | NilLiteralSource

Resolves this path to a TypeNode if it denotes a type, or otherwise returns a NilLiteral.

def type_vars : ArrayLiteral(ASTNode)Source

Returns the arguments (the type variables) of this instantiation.

def types : ArrayLiteral(ASTNode)Source

Returns this generic inside an array literal. This method exists so you can call #types on the type of a type declaration and get all types, whether it's a Generic, Path or Union.
