1/// Represents which edges of the output a layer surface should be anchored to.
2///
3/// Use predefined helpers like `top_bar()`, `bottom_bar()`, or build custom configurations
4/// with `empty()` combined with `with_top()`, `with_bottom()`, `with_left()`, `with_right()`.
5///
6/// # Examples
7/// ```
8/// use layer_shika_domain::value_objects::anchor::AnchorEdges;
9///
10/// let top_bar = AnchorEdges::top_bar();
11/// let custom = AnchorEdges::empty().with_top().with_left();
12/// ```
