Q# Structs: Declaration and Constructor Syntax

ScottCarda-MS commented 1 month ago

Declaration and Constructor syntax for Q# structs.

Structs can be declared as namespace items with the following syntax:

struct Pair {
    First : Int,
    Second : Int
}

Structs types that have been declared can be constructed using the following expression syntax:

new Pair { First = 3, Second = 4 }

Additionally, structs can be constructed from other structs using the following copy constructor syntax:

new Pair { ...existing_pair }

and specific fields can be altered while copying:

new Pair { ...existing_pair, Second = 7 }
