Expand description
The abstract syntax tree (AST) of Jsonnet code.
Since Jsonnet is a purely functional language, it is composed mainly of
expressions. See Expr and ExprKind as starting point.
§Lifetimes
AST structures in this module are intended to be allocated with arena allocation. Two lifetime are used:
'p, which represents interned strings.'ast, which represents most allocations of AST nodes.
Independent arenas can be used for each lifetime, allowing to free most of an AST while keeping interned strings.
