Enum PathSeg 

pub enum PathSeg {
    Key(String),
    Index(u32),
}

A single step in a JSON -> path expression.

This is the query-crate’s OWNED path-segment type (distinct from powdb_storage::pj1::PathSeg, which borrows &str keys). Segments are STRUCTURAL: they are part of the query shape, never literal slots, so the plan cache hashes them into the canonical token stream and neither counts nor substitutes them (see plan_cache::count_expr / substitute_expr).

Variants

Key(String)

Object member access: ->author or ->"weird key!".

Index(u32)

Array element access: ->0.
