[src]
pub fn is_descendant_of(self, ancestor: Mark) -> bool
pub fn least_ancestor(a: Mark, b: Mark) -> Mark
[src]
pub fn least_ancestor(a: Mark, b: Mark) -> Mark
Computes a mark such that both input marks are descendants of (or equal to) the returned mark. That is, the following holds:
let la = least_ancestor(a, b); assert!(a.is_descendant_of(la)) assert!(b.is_descendant_of(la))
