Struct GraphStep 

pub struct GraphStep {
    pub targets: Vec<Spanned<String>>,
    pub where_clause: Option<Box<Spanned<Expr>>>,
    pub reference: bool,
}

The selection inside one graph step. SurrealDB allows a full mini-select here (multiple edge tables, WHERE, ORDER, LIMIT, alias, …) — we model what analysis consumes (targets + filter) and bucket the rest.

Fields

targets: Vec<Spanned<String>>

One or more edge tables: ->likes or ->(likes, follows).

where_clause: Option<Box<Spanned<Expr>>>

->(likes WHERE since > $x) / ->likes[WHERE ...].

reference: bool

The step is a record-reference traversal (<~), not a graph-edge traversal (<-/->/<->). Reference steps follow REFERENCE fields rather than relation tables, so typing resolves them differently.
