Struct Field 

pub struct Field {
    pub name: String,
    pub keys: Vec<IndexExpr>,
}

A single field in a path expression.

Each field has a name and zero or more index keys. For example, in the path resource.attributes["key"], there are two fields: Field { name: "resource", keys: [] } and Field { name: "attributes", keys: [IndexExpr::String("key")] }.

Pre-allocated at parse time and stored in [ResolvedPath]; on the hot path the evaluator passes &[Field] by reference with zero allocation and zero copy.

Fields

name: String

Identifier for this field segment.

keys: Vec<IndexExpr>

Index keys attached to this field (e.g. ["key"], [0]).
