Struct ExprPathStep 

#[non_exhaustive]
pub struct ExprPathStep {
    pub node_id: u32,
    pub operator: Option<String>,
    pub arg_index: Option<u32>,
    pub json_pointer: String,
}

One step in a compiled expression’s structural evaluation path, from root to failing node.

Mirrors datalogic_rs::PathStep with PartialEq + Eq so a host can persist, compare, or inspect where inside a rule an evaluation failed without re-parsing a display string.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

node_id: u32

Compile-time node id, matching datalogic_rs::Error::node_ids.

operator: Option<String>

Operator name at this node, when one applies.

arg_index: Option<u32>

Zero-based position within the parent node’s argument list.

json_pointer: String

JSONLogic-flavoured pointer from the root to this node (e.g. "/if/0/>/0").
