Enum OriginalNode 

pub enum OriginalNode {
    Expression(Box<Expression>),
    Statement(Box<Statement>),
    Pattern(Box<PatternLike>),
}

An original source AST node preserved verbatim for re-emission when the compiler bails on a construct it does not model (UnsupportedNode).

Holding the typed node directly — rather than a serde_json::Value — lets lowering stash it and codegen restore it without round-tripping through serde, which is what kept the AST (de)serializers out of the generated binary. The variant records which syntactic position the node came from, so codegen can dispatch without re-parsing a type tag.

Variants

Expression(Box<Expression>)

Statement(Box<Statement>)

Pattern(Box<PatternLike>)
