Enum PathStep 

#[non_exhaustive]
pub enum PathStep {
    PathProject(PathExpr),
    PathIndex(PathExpr),
    PathForEach,
    PathUnpivot,
}

A “step” within a path expression; that is the components of the expression following the root.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

PathProject(PathExpr)

PathIndex(PathExpr)

PathForEach
