§Panics

頂点iと頂点jが隣接していないときパニックする。

頂点iと頂点jの間に辺を張る。

§Panics

頂点iと頂点jが同一の木に属するときパニックする。

Source

pub fn evert(&mut self, k: usize)

Source

pub fn set(&mut self, k: usize, x: M)

頂点kの値をxに変更する。

Source

pub fn update(&mut self, k: usize, x: M)

頂点kの値をモノイドの演算と値xで更新する。

Source

pub fn get(&self, k: usize) -> M
