Expand description

Represents a constant assignment (i.e. A = 1)

Fields

scope: Option<Box<Node>>

Scope where the constant is defined: 1. Some(Const("A")) for A::B = 1 2. None if it’s defined in the current scope (i.e. A = 1) 3. Some(Cbase) if it’s defined in the global scope (i.e. ::A = 1)

name: String

Name of the constant, String("A") for A = 1

value: Option<Box<Node>>

Value that is assigned to a constant, Int("1") for A = 1.

Note: None if constant assignment is a part of the multi-assignment. In such case value belongs to Masgn node of the multi-assignment.

double_colon_l: Option<Loc>

Location of the :: operator

A::B = 1
 ~~

::A = 1
~~

None if the constant is defined in the current scope

name_l: Loc

Location of the constant name

A::CONST = 1
   ~~~~~
operator_l: Option<Loc>

Location of the = operator

A = 1
  ~

None if constant assignment is a part of the multi-assignment. In such case = belongs to a Masgn node

expression_l: Loc

Location of the full expression

A = 1
~~~~~
