Validates a property is within a given Range.

Optional Arguments


class Example
  include Assert

  def initialize; end

  @[Assert::InRange(Range(Float64, Nil), range: 0.0..)]
  property minimum_only : Int32 = 27

  @[Assert::InRange(Range(Nil, Int64), range: ..100_000_000_000)]
  property maximum_only : Int32 = 50_000

  @[Assert::InRange(Range(Float64, Float64), range: 0.0..1000.0)]
  property range : Float64 = 3.14

  @[Assert::InRange(Range(Int32, Int32), range: 0..10, not_in_range_message: "That is not a valid %{property_name}")]
  property fav_number : UInt8 = 8_u8

  @[Assert::InRange(Range(UInt8, UInt8), range: 0_u8..50_u8, min_message: "Number of cores must be positive", max_message: "There must be less than 50 cores")]
  property cores : Int32 = 32
end # => true
