Function Documentation

fnv1aData()

constexpr uint64_t fnv1aData ( const void *  data, size_t  len, uint64_t  seed = 0xcbf29ce484222325ULL  )

constexpr

Computes the FNV-1a hash of a block of data.

Iterates over a byte range and applies the FNV-1a mixing step to each byte. The function is constexpr for use in constant expressions.

Parameters

data	Pointer to the input data.
len	Length of the input data in bytes.
seed	Initial hash value (defaults to the FNV offset basis).

Returns

The 64-bit FNV-1a hash.
