Returns a Boolean value indicating whether two values are equal.

Equality is the inverse of inequality. For any values a and b, a == b implies that a != b is false.

The close event of this period. Can be nil if period is open 24hrs.

A textual representation of this instance.

Calling this property directly is discouraged. Instead, convert an instance of any type to a string by using the String(describing:) initializer. This initializer works with any type, and uses the custom description property for types that conform to CustomStringConvertible:

struct Point: CustomStringConvertible {
    let x: Int, y: Int

    var description: String {
        return "(\(x), \(y))"
    }
}

let p = Point(x: 21, y: 30)
let s = String(describing: p)
print(s)
// Prints "(21, 30)"

The conversion of p to a string in the assignment to s uses the Point type’s description property.

Hashes the essential components of this value by feeding them into the given hasher.

Implement this method to conform to the Hashable protocol. The components used for hashing must be the same as the components compared in your type’s == operator implementation. Call hasher.combine(_:) with each of these components.

The hash value.

Hash values are not guaranteed to be equal across different executions of your program. Do not save hash values to use during a future execution.

The open event of this period.

Each Period is guaranteed to have an open event. If the period is representing open 24hrs, it will only have the open Event with time as “0000”.
