Declaration

public static Hash128 Compute(ref T val);

Declaration

public static Hash128 Compute(int val);

Declaration

public static Hash128 Compute(float val);

Parameters

Parameter	Description
val	Input value.

Returns

Hash128 The 128-bit hash.

Description

Compute a hash of input data.

The value must be an "unmanaged" C# type. Primitive types like int, float, bool, enums, pointers, or structs containing primitive types are all unmanaged types. See Unmanaged types in C# language reference.

The int and float overloads use a dedicated hashing code path that is optimized for 4-byte data sizes.

using UnityEngine;public class ExampleScript : MonoBehaviour
{
    void Start()
    {
        var data = new Vector3(1.5f, 7.0f, 42.0f);
        var hash = Hash128.Compute(ref data);
        // prints "abc99ce06a8d7acca0714cd64d661808"
        Debug.Log(hash.ToString());
    }
}

Declaration

public static Hash128 Compute(string data);

Parameters

Parameter	Description
data	Input data string. Note that Unity interprets the string as UTF-8 data, even if internally in C# strings are UTF-16.

Returns

Hash128 The 128-bit hash.

Description

Compute a hash of input data string.

using UnityEngine;public class ExampleScript : MonoBehaviour
{
    void Start()
    {
        var hash = Hash128.Compute("The quick brown fox jumps over the lazy dog");
        // prints "c79306aa46e8122b1b340724747e361d"
        Debug.Log(hash.ToString());
    }
}

Declaration

public static Hash128 Compute(T[] data);

Declaration

public static Hash128 Compute(List<T> data);

Declaration

public static Hash128 Compute(NativeArray<T> data);

Parameters

Parameter	Description
data	Input data array.

Returns

Hash128 The 128-bit hash.

Description

Compute a hash of input data.

using UnityEngine;public class ExampleScript : MonoBehaviour
{
    void Start()
    {
        var data = new byte[] { 10, 20, 30, 40, 50 };
        var hash = Hash128.Compute(data);
        // prints "6e8dd00dc1d495a01d9e6dbffcd174b2"
        Debug.Log(hash.ToString());
    }
}

Declaration

public static Hash128 Compute(T[] data, int start, int count);

Declaration

public static Hash128 Compute(List<T> data, int start, int count);

Declaration

public static Hash128 Compute(NativeArray<T> data, int start, int count);

Parameters

Parameter	Description
data	Input data array.
start	The first element in the data to start hashing from.
count	Number of array elements to hash.

Returns

Hash128 The 128-bit hash.

Description

Compute a hash of a slice of input data.

using UnityEngine;public class ExampleScript : MonoBehaviour
{
    void Start()
    {
        var data = new byte[] { 0, 10, 20, 30, 40, 50, 60 };
        // will hash bytes: 10, 20, 30, 40, 50
        var hash = Hash128.Compute(data, 1, 5);
        // prints "6e8dd00dc1d495a01d9e6dbffcd174b2"
        Debug.Log(hash.ToString());
    }
}

Declaration

public static Hash128 Compute(void* data, ulong size);

Parameters

Parameter	Description
data	Raw data pointer, usually used with C# `stackalloc` data.
size	Data size in bytes.

Returns

Hash128 The 128-bit hash.

Description

Compute a hash of input data.
