Count

public struct Count : Countable, ExpressibleByIntegerLiteral

Count object. Use it for all Verify features, when checking how many times something happened.

There are three ways of using it:

  1. Explicit literal - you can pass 0, 1, 2 … to verify exact number
  2. Using init with closure, to specify matching rule like: Count() { return ... }
  3. Using one of predefined rules, for example:
    • .never
    • .atLeastOnce
    • .in(range: 0…3)
    • .in(range: 1..<3)
    • .in(range: 7…)
    • .more(than: 2)
    • .moreOrEqual(to: 3)
    • .less(than: 2)
    • .lessOrEqual(to: 1)

  • [Internal] Count is represented by integer literals, with type Int

    Declaration

    Swift

    public typealias IntegerLiteralType = Int

  • Creates new count instance, matching specific count

    Declaration

    Swift

    public init(integerLiteral value: IntegerLiteralType)

    Parameters

    value

    Exact count value

  • Creates new count instance, with given way of checking, whether count is right or not

    Declaration

    Swift

    public init(match: @escaping (Int) -> Bool)

    Parameters

    match

    Count matching closure

  • Returns whether given count matches countable case.
