Random Service

Contains a Random Service that provides an IRandomizer abstraction whose contract is equivalent to System.Random.

Features

• New random number generators based on System.Random:

  • ConcurrentPseudoRandom - A random number generator guaranteeing thread safety;
  • CryptoRandom - A random number generator based on the System.Security.Cryptography.RNGCryptoServiceProvider.

• Supported types:

  1. Int32/Int
  2. Double
  3. Byte[]

• Supported types via extension methods:

  1. SByte
  2. Byte
  3. Int16/Short
  4. UInt16/UShort
  5. UInt32/UInt
  6. Int64/Long
  7. UInt64/ULong
  8. Float
  9. Decimal
  10. Char[]
  11. String
  12. Boolean
  13. Enum

• Extensibility (see Depra.Unity.Random);

• Most of the functionality is covered by unit tests;

• Also included are benchmarks that may be of interest.

Usage

To instantiate a service you need to use the builder pattern.

Instance creation with a custom randomizer:

var randomService = new RandomServiceBuilder()
                .With<int>(new CutomIntRandomizer()) // Or another randomizer
                .Build();                            // for type Int32

Instantiating with a collection of randomizers:

var randomService = new RandomServiceBuilder()
                .With(new PseudoRandomizers()) // Or another collection of randomizers. 
                .Build();

// You can get randomizers from collections working with System.Random in this way:
var intRandomizer = randomService.GetRandomizer(typeof(int))
intRandomizer = randomService.GetNumberRandomizer<int>();
var doubleRandomizer = randomService.GetTypedRandomizer<double>();
var byteArrayRandomizer = randomService.GetArrayRandomizer<byte[]>();

With the help of extension methods for randomizers, you can also get random value types that are not supported through System.Random. An example of getting a random string using INumberRandomizer:

var intRandomizer = randomService.GetNumberRandomizer<int>();
var randUpperCaseString = intRandomizer.NextString(length: 10, includeLowerCase: false);
var randString = intRandomizer.NextString(length: 20, allowedCharacters: "abcdef");

Integrations:

• Depra.Unity.Random - To provide support for UnityEngine.Random.

Ps

Some extension methods may not perform well and will be improved in future releases.

Your suggestions for improvements are welcome.
