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
~~~~~

Trait Implementations

impl Clone for Casgn

fn clone(&self) -> Casgn

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Casgn

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl PartialEq for Casgn

fn eq(&self, other: &Casgn) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
