pub struct DeclareVarStmt<Type, Expr>(pub Type, pub Expr);

Declares a new variable. Renders as Type Expr; with a new line at the end The expression can be either the variable name or an AssignExpr.

let declare_var = DeclareVarStmt(Str("String"), Str("varname"));
let string = InMemoryOutput::print_output(EmptyContext, &declare_var);
assert_eq!("String varname;\n", string);

let init_var = DeclareVarStmt(Str("String"), AssignExpr(Str("varname"), Str("\"hello world\"")));
let string = InMemoryOutput::print_output(EmptyContext, &init_var);
assert_eq!("String varname = \"hello world\";\n", string);
