pub enum StepFilter {
    Any,
    EdgeType(EdgeType),
    EdgeTypes(Vec<EdgeType>),
    Custom(String),
}

EdgeType(EdgeType)

Match edges of a specific type.

EdgeTypes(Vec<EdgeType>)

Match edges of any of these types.

Custom(String)

Custom filter with a predicate function. Note: This variant stores a descriptive string for debugging.
