Expand description
let <something> = <something else>
.
Defines variables and possibly adds rules to them.
Fields§
§let_token: Let

eq: Eq
The =
token.
expr: Expression<true>
The rhs expression.
rule: Option<(RuleOperator, Expression<true>)>
The rule after the rhs expression.
semi: Semi
The ending semicolon.
