Struct segment_tree::ops::Add

pub struct Add;

Each node contains the sum of the interval it represents.

Trait Implementations

impl<T: Add<Output = T> + Copy> Operation<T> for Add

fn combine(a: &T, b: &T) -> T

The operation that is performed to combine two intervals in the segment tree.

fn combine_mut(a: &mut N, b: &N)

Replace the value in a with combine(a, b). This function exists to allow certain optimizations and by default simply calls combine.

fn combine_mut2(a: &N, b: &mut N)

Replace the value in a with combine(a, b). This function exists to allow certain optimizations and by default simply calls combine.

fn combine_left(a: N, b: &N) -> N

Must return the same as combine. This function exists to allow certain optimizations and by default simply calls combine_mut.

fn combine_right(a: &N, b: N) -> N

Must return the same as combine. This function exists to allow certain optimizations and by default simply calls combine_mut2.

fn combine_both(a: N, b: N) -> N

Must return the same as combine. This function exists to allow certain optimizations and by default simply calls combine_left.

impl<T: Sub<Output = T> + Copy> Inverse<T> for Add

fn uncombine(a: &mut T, b: &T)

Returns some value such that combine(uncombine(a, b), b) = a.
