Module ops

Module of operations that can be performed in a segment tree.

A segment tree needs some operation, and this module contains the main Operation trait, together with the marker trait Commutative. This module also contains implementations for simple operations.

Structs

Add

Each node contains the sum of the interval it represents.

And

Each node contains the bitwise and of the interval it represents.

Max

Each node contains the maximum of the interval it represents.

MaxIgnoreNaN

Variant of Max that considers NaN the smallest value.

MaxTakeNaN

Variant of Max that considers NaN the largest value.

Min

Each node contains the minimum of the interval it represents.

MinIgnoreNaN

Variant of Min that considers NaN the largest value.

MinTakeNaN

Variant of Min that considers NaN the smallest value.

Mul

Each node contains the product of the interval it represents.

Or

Each node contains the bitwise or of the interval it represents.

Pair

Store several pieces of information in each node.

Xor

Each node contains the bitwise xor of the interval it represents.

Traits

Commutative

A marker trait that specifies that an Operation is commutative, that is: combine(a, b) = combine(b, a).

Identity

A trait that specifies that this Operation has an identity element.

Invertible

A trait for invertible operations.

Operation

A trait that specifies which associative operator to use in a segment tree.
