Hash128(void*, long)
Compute a 128bits hash of a memory region
public static uint4 Hash128(void* input, long length)
Parameters
Returns
Type | Description |
|---|---|
| uint4 | The hash result |
Hash128<T>(T)
Compute a 128bits hash from the contents of the input struct
public static uint4 Hash128<T>(in T input) where T : unmanaged
Parameters
Returns
Type | Description |
|---|---|
| uint4 | The hash result |
Hash128(void*, void*, long)
Compute a 128bits hash while copying the data to a destination buffer
public static uint4 Hash128(void* input, void* destination, long length)
Parameters
Returns
Type | Description |
|---|---|
| uint4 | The hash result |
Remarks
Use this API to avoid a double memory scan in situations where the hash as to be compute and the data copied at the same time. Performances improvements vary between 30-50% on big data.
Hash128(void*, long, ulong)
Compute a 128bits hash of a memory region using a given seed value
public static uint4 Hash128(void* input, long length, ulong seed)
Parameters
Returns
Type | Description |
|---|---|
| uint4 | The hash result |
Hash128(void*, void*, long, ulong)
Compute a 128bits hash while copying the data to a destination buffer using a given seed value
public static uint4 Hash128(void* input, void* destination, long length, ulong seed)
Parameters
The memory buffer to compute the hash and copy from, can't be null
The destination buffer, can't be null and must be at least big enough to match the input's length
The length of the memory buffer, can be zero
The seed value to alter the hash computation from
Returns
