Struct IntersectionView 

pub struct IntersectionView { /* private fields */ }

The conjunction of several filters: an attribute is visible only when every part admits it.

This is how the evaluator combines the views of several successful paths — intersecting visibility constraints rather than taking the widest, so holding one more relation can never reveal more than holding it alone.

Implementations

impl IntersectionView

pub fn new(parts: Vec<Arc<dyn ViewFilter>>) -> Self

Intersects parts.

Trait Implementations

impl Clone for IntersectionView

fn clone(&self) -> IntersectionView

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for IntersectionView

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl ViewFilter for IntersectionView

fn attribute_visible(&self, attribute: &str) -> bool

Whether datoms of attribute (a keyword ident like :person/email) are visible to the principal.
