Struct Step 

pub struct Step {
    pub axis: Axis,
    pub node_test: NodeTest,
    pub predicates: Vec<Expr>,
    pub filter: Option<Box<Expr>>,
}

Fields

axis: Axis

node_test: NodeTest

predicates: Vec<Expr>

filter: Option<Box<Expr>>

XPath 2.0 StepExpr ::= AxisStep | FilterExpr. When Some, the step is a FilterExpr (a primary expression like a function call or parenthesised expression) that produces its own sequence per input node — axis and node_test are unused for the eval but kept at their default (Self_ / AnyNode) so existing code that destructures Step directly still type-checks. path/key('x', 'y') and path/(expr) parse into this shape.
