Instance Method Detail

def name : Path #

Returns the path to the generic.

def named_args : NamedTupleLiteral | NilLiteral #

Returns the named arguments of this instantiation, if any.

[View source]
def resolve : ASTNode #

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

[View source]
def resolve? : ASTNode | NilLiteral #

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

def type_vars : ArrayLiteral(ASTNode) #

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

[View source]
def types : ArrayLiteral(ASTNode) #

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.
